(ANNOUNCER)>> TODAY ON
ENGINE POWER, THE GUYS TACKLE CHRYSLER'S MOST
DURABLE AND VERSATILE INLINE SIX WITH A TWIST,
OR SHOULD WE SAY A SLANT.
(MIKE)>> LEGENDARY FOR BEING INDESTRUCTIBLE, TODAY WE'RE GOING TO DISSECT, REBUILD, AND HOP UP A TRUE AMERICAN CULT ENGINE, THE BULLET PROOF CHRYSLER SLANT SIX. WHY YOU MAY ASK? WELL IT'S A POPULAR ENGINE SEVERAL OF YOU VIEWERS HAVE BEEN ASKING US TO GO THROUGH. ITS REVOLUTIONARY INLINE SIX DESIGN IS TILTED 30 DEGREES OFF CENTER TO ALLOW A LOWER HOOD PROFILE, A LOWER CENTER OF GRAVITY, AND MORE ACCESS TO ENGINE ACCESSORIES. FROM 1959 TO 2000, MOPAR PRODUCED OVER 12 MILLION OF THESE "G" SERIES ENGINES IN 170, 198, AND 225 CUBIC INCH DISPLACEMENTS. FIRST FOR THE COMPACT VALIANT, AND THEN AS THE BASE ENGINE IN OVER 25 DODGE AND PLYMOUTH CARS AND TRUCKS FROM DARTS TO DIPLOMATS, AND BELVEDERES TO BARRACUDAS. AND THANKS TO ITS EXTREME RELIABILITY, THE SLANT SIX ALSO SAW DUTY IN SCORES OF TRACTORS, MILITARY TRUCKS, FORK LIFTS, AND INDUSTRIAL APPLICATIONS.
(PAT)>> WE PICKED THIS ONE UP AT THE LOCAL BONEYARD FOR $150 BUCKS. AND WHILE IT'S NOT GOING TO PERFORM LIKE A VEIGHT, THIS LEANING TOWER OF POWER IS HIGH IN THE COOL DEPARTMENT. BUT I THINK IT HAS SOME ISSUES. THE DISTINCTIVE UNEQUAL LENGTH INTAKE RUNNERS WERE MEDIOCRE AT DISTRIBUTING FUEL, BUT THEY STILL DELIVERED OVER 30 MILES PER GALLON AND 145 HORSES AT 4,000 RPM, AND A VERY TORQUEY 215 FOOT POUNDS AT JUST 2,800. GOD THIS THING WEIGHS A TON. CRACKS IN SLANT SIX EXHAUST MANIFOLDS WERE VERY COMMON. THIS ONE FITS RIGHT IN. THE VALVE COVER HAS SEEN BETTER DAYS BUT ITS NOT GOING TO THE SCRAP PILE YET. WE'LL USE ALL THE OLD TINS AS COVERS WHEN WE GIVE IT A PAINT JOB. NEXT TO COME UP IS THE CANNON OIL PAD. SEVERAL VERSIONS WERE MADE DEPENDING ON WHAT VEHICLE THEY WENT INTO AND THE CAPACITY RANGED FROM FIVE TO SIX QUARTS. THE PICK UP IS SCREWED INTO THE BLOCK, AND IT CAN BE REMOVED AS WELL. UP FRONT THE BALANCER CAN BE REMOVED
USING OUR MATCO PULLER. THE STAMPED STEEL TIMING COVER COMES OFF NEXT. SINCE THIS WAS A CAR ENGINE, AND NOT A HEAVY
DUTY VERSION, IT HAS A SINGLE ROW TIMING CHAIN. WE'LL BE REPLACING EVERYTHING ON THE SIDE OF THE ENGINE, THE COIL, THE FUEL PUMP, THE
DISTRIBUTOR, AND ENGINE MOUNT.
CHRYSLER FITTED THIS ENGINE WITH AN EXTERNAL GEAR ROTOR TYPE OIL PUMP. IT'S DESIGN AND LOCATION MADE IT EASILY SERVICEABLE EVEN THOUGH NOT MANY PROBLEMS AROSE. 225'S WERE EQUIPPED WITH EITHER A STANDARD VOLUME LIKE THIS ONE, OR A HIGH VOLUME ONE IN HEAVY DUTY MODELS. THE VALVETRAIN FEATURES ADJUSTABLE SHEET METAL ROCKER ARMS WITH A ONE POINT FIVE RATIO. THEY'RE HELD IN PLACE WITH A SHAFT, WHICH IS HOW THEY'RE LUBRICATED. THE CYLINDER HEAD IS CONSTRUCTED OF CHROME ALLOY CAST IRON. REMOVING THE HEAD BOLTS IN THE REVERSE ORDER OF HOW THEY WERE TORQUED WILL KEEP THE HEAD FROM WARPING LIKE A BANANA. LET'S SEE WHAT WE'VE GOT.
(MIKE)>> COUNTLESS YEARS IN THE SALVAGE YARD LET THIS SLICK SIX SOAK IN PLENTY OF WATER. UNFORTUNATELY IT'S TAKEN ITS TOLL. NOW WE DON'T EVEN KNOW IF THIS BLOCK WILL BE SERVICEABLE DUE TO THE AMOUNT OF CORROSION. AT THIS POINT A LOT OF GUYS WOULD GO AHEAD AND SCRAP THIS BLOCK, BUT WE'RE NOT GIVING UP. PLUS A LITTLE BIT OF DESTRUCTION DOESN'T SCARE US AS LONG AS IT MOVES US ON TO THE NEXT STEP. SO THE OLD AIR CHISEL IS COMING OUT OF HIDING. WE NEED TO SEE IF THE FACTORY FORGED CRANK SHAFT
WILL COME OUT WITHOUT REMOVING THE RODS. SO FIRST WE'LL REMOVE ALL OF THE ROD CAPS, FOLLOWED BY THE MASSIVE MAINS. NOW THESE SHARE THE SAME DESIGN AND SIZE FROM
CHRYSLER'S HEMI VEIGHT.
(PAT)>> YOU READY? OH, YEP!
(MIKE)>> NICE!
(PAT)>> THAT IS GOING TO MAKE IT WAY EASIER.
(MIKE)>> ON CYLINDERS ONE AND TWO, THEY CAME OUT RELATIVELY EASY BECAUSE THE VALVES WERE CLOSED ON THOSE CYLINDERS, KEEPING THE WATER OUT. HEY YOU CLEAN THE BORE PRETTY GOOD ON THE WAY OUT.
[ air chisel vibrating ]
(MIKE)>> AS WE PROGRESSED, SO DID THE DEGREE OF DIFFICULTY, BUT IT CAME OUT WITH A LITTLE VIBRATORY PERSUASION.
(PAT)>> WOW!
(MIKE)>> NUMBER FOUR WAS THE MOST STUBBORN. THE PISTON'S MOVING BUT IT'S NOT GOING DOWN.
(PAT)>> IT'S ROCKING. OUR EFFORTS WEREN'T WORKING, SO WE'RE GONNA HAVE TO GET MORE AGGRESSIVE WITH IT. AND BEFORE WE COMPLETELY BLAST THE PISTON OUT WITH
A CHISEL, WE'RE GONNA PUT A PLATE FLAT ON THE ROD AND HIT STRAIGHT DOWN TO SEE IF WE
CAN JAR IT LOOSE. UM, YOU MOVED IT! [ air chisel vibrating ]
(PAT)>> YEAH BABY!
(MIKE)>> I CAN'T BELIEVE THAT.
(PAT)>> THAT WAS AWESOME!
(MIKE)>> THE FINAL TWO HAD THE MOST CORROSION AND BUILD UP ON THE CYLINDER WALL.
(PAT)>> WE HAVE NO IDEA HOW MANY MILES. IT COULD HAVE A GAZILLION MILES ON IT.
(MIKE)>> I'M KINDA SICK AND TIRED OF VIBRATING. LET'S GET THIS LAST ONE OUT AND THEN WE'LL TALK ABOUT IT.
(PAT)>> I LOVE SCIENCE, I LOVE DISCOVERY.
(MIKE)>> THEY MOVED EASIER THAN THREE AND FOUR, BUT THE RUST CLOUD TELLS THE WHOLE STORY.
(PAT)>> HOLY MOLY!
(MIKE)>> BUT KNOCKING THE PISTONS OUT AT THE TOP, IT GAVE US A CLEANER AND BETTER VIEW TO CHECK
THE CONDITION OF THESE CYLINDERS. AS FAR AS WE CAN TELL, THEY MAY BE SALVAGEABLE. THE WATER PUMP IS MOUNTED WITH A LATERAL OFFSET, WHICH HELPED KEEP THE ENGINE AS SHORT AS POSSIBLE. NOW THEY DID HAVE A KNOWN ISSUE, THE SHAFT WOULD SHEAR OFF OF THE PUMP.
(PAT)>> OH MAN, THAT IS INFANT DIARRHEA.
(MIKE)>> THE CAM SHAFT IS STANDARD FAIR SIX CYLINDER THAT RIDES ON FOUR CAM BEARING JOURNALS AND HAS THE DISTRIBUTOR DRIVE IN THE MIDDLE. NOW IT'S BEING UPGRADED FOR A PEPPIER GRIND FROM COMP CAMS. THE LAST THING WE'RE GONNA DO IS GO AHEAD AND WASH THIS BLOCK BEFORE WE SEND IT OFF TO THE MACHINE SHOP. THAT'S GONNA GIVE THOSE GUYS A HEAD START WITH A CLEAN PIECE.
(ANNOUNCER)>> IT'S NOT REBUILDABLE UNTIL THE MACHINE SHOP SAYS IT IS.
(MIKE)>> WE'RE BACK, AND A WEEK HAS PASSED SINCE WE SENT OUR SLANT SIX OUT TO THE MACHINE SHOP, BUT IT DIDN'T MAKE IT BACK. THE MACHINE SHOP FOUND TOO MANY THINGS WRONG WITH IT AND IT WAS JUST FLAT OUT UNUSABLE. SO WE'RE GONNA GO AHEAD AND MOVE FORWARD WITH THIS ONE.
BEFORE WE START ASSEMBLING IT, A FEW COATS OF DUPLICOLOR CERAMIC ENGINE ENAMEL IN CHRYSLER RED WERE IN ORDER.
(PAT)>> THE ORIGINAL CRANK HAD A CRACK IN THE RADIUS OF THE ROD JOURNAL ON CYLINDER NUMBER ONE, WHICH IS AUTOMATIC GROUNDS FOR REPLACEMENT. SINCE OUR PLAN IS TO HAVE A STREET FRIENDLY SLANT SIX WITH EXCELLENT DRIVABILITY, A FORGED CRANK WOULD BE OVERKILL FOR THE APPLICATION. SO A CAST CRANK LIKE THIS ONE WILL BE PLENTY STRONG ENOUGH FOR THE RPM AND POWER WE'RE GONNA MAKE.
(MIKE)>> MATCHING RODS WERE ALSO NEEDED FOR THAT CAST CRANK. THAT'S DUE TO THE BIG END BEING NARROWER. NOW ON THE FORGED CRANK IT WAS A LOT WIDER, BUT THEY DO SHARE THE SAME CENTER TO CENTER LENGTHS. THE EARLY MODEL BLOCK HAD THREE FREEZE PLUGS ON THE SIDE OF IT. THIS ONE IS A LATER VERSION AND HAS FIVE.
DIMENSIONALLY THERE ARE NO DIFFERENCES.
(PAT)>> THE INGREDIENTS FOR THIS BUILD ARE ALL AFFORDABLE BOLT ON PARTS YOU CAN BUY THROUGH SUMMIT RACING. NAMES LIKE COMP CAMS, EDELBROCK, PIONEER, HOOKER, AND OFFENHAUSER WILL HELP US MAKE MORE POWER. EVEN THOUGH IT'S FRESH FROM THE MACHINE SHOP, IT'S ALWAYS PROPER ENGINE BUILDING PRACTICE TO CHECK YOUR TOLERANCES. SINCE IT'S NOT A HIGH TECH RACING ENGINE, THESE MEASUREMENTS WILL BE A LITTLE MORE FORGIVING. FIRST WE'RE GOING TO CHECK THE MAIN BEARINGS. OUR REPLACEMENT CRANK CLEANED UP AT 10 THOUSANDTHS UNDERSIZED ON THE MAINS. I'LL USE A TWO TO THREE MIC TO LOCK IN THE EXACT SIZE OF THE JOURNAL. NOW THE NUMBER ONE MAIN CAN BE FILLED WITH A BEARING AND TORQUED INTO PLACE. I'LL SET THE DIAL BORE GAUGE UP USING THE MIC AND CHECK THE TORQUE MAINS TO MEASURE THE CLEARANCE. I'LL REPEAT THIS FOR THE OTHER THREE MAINS AS WELL. DON'T EVER ASSUME THINGS WILL ALWAYS BE RIGHT. OEM STUFF ALSO HAS A LARGER WINDOW OF ACCEPTABLE CLEARANCES FOR BEARINGS, UNLIKE A TRUE RACE ENGINE.
ALL THE ROD JOURNALS GET MEASURED NEXT, AND THE SAME PROCEDURE IS USED TO CHECK OIL CLEARANCE FOR THE ROD BEARINGS. I'LL TORQUE THE RODS IN A SPECIAL VICE, AND THEN USE THE DIAL BORE GAUGE TO CHECK ALL THEIR CLEARANCES. IF YOU'VE NEVER DONE THIS BEFORE HERE'S SOME INTERESTING INFO YOU SHOULD KNOW. THE FACTORY BEARING CLEARANCES FOR A SLANT SIX ON BOTH THE MAIN AND ROD BEARINGS RANGES FROM TWO-10 THOUSANDTHS TO 22-10 THOUSANDTHS. THAT'S A TWO THOUSANDTHS RANGE, WHICH IS HUGE BY MACHINING STANDARDS. OURS ARE COMING IN ALMOST DEAD IN THE MIDDLE, WHICH IS RIGHT WHERE WE WANT. THE REAR MAIN SEAL I'M PUTTING IN IS SOMETHING SPECIAL AVAILABLE FROM FAST FISH AUTO PARTS. HEMI SPECIALIST JEFF GUNTHER CREATED THIS SEAL TO FIX THE AGE OLD PROBLEM OF THE LEAKY REAR MAIN SEAL ON BIG BLOCK MOPARS. SINCE THIS SLANTY SHARES THE SAME MAIN JOURNAL SIZE AS A HEMI, IT'S A FANTASTIC UPGRADE. FOLLOW THE INSTRUCTIONS TO A "T" AND YOU'LL HAVE NO ISSUES.
FINALLY IT'S TIME TO LAY THE CRANK IN. ROYAL PURPLE MAX TOUGH LUBE IS PUT ON THE BEARINGS, AND 80 PLUS POUNDS WORTH OF IRON IS SET IN ITS PLACE. THE SEAL GETS A DAB OF RTV AND IS ROTATED SO THE PARTING LINE IS INSIDE THE BLOCK. GOING FROM THE INSIDE OUT, THE MAIN BOLTS ARE TORQUED TO 70 FOOT POUNDS.
(MIKE)>> TO FINISH UP THE CRANK INSTALL WE NEED TO PREP THE REAR MAIN SEAL RETAINER. A LITTLE BIT OF LOCTITE ON THE BOLT'S THREADS AND SOME SILICONE ON THE SIDE SEALS, IT'S READY TO GO IN.
AFTER EASING IT INTO PLACE, WE CAN LOCK IT DOWN BY TORQUING IT TO 30 FOOT POUNDS. LAST BUT CERTAINLY NOT LEAST IS THE CRANK'S END PLAY. NOW THE FACTORY RANGE WAS FRONT TWO TO SEVEN THOUSANDTHS. THIS ONE CHECKS IN AT A COMFORTABLE FIVE THOUSANDTHS.
(MIKE)>> WE'RE BACK AT IT AND OUR LEANING TOWER OF POWER IS READY FOR MORE PARTS. NOW IT'S TIME TO PREP THE PISTON AND ROD ASSEMBLIES. FIRST MAKE SURE THE DOTS ON THE RINGS ARE FACING THE TOP OF THE PISTON. SECOND, THE RING GAPS NEED TO BE CLOCKED SO THEY DO NOT ALIGN. NOW IF THOSE RINGS DO ALIGN, YOU CAN GET EXCESSIVE BLOW BY, WHICH CAUSES CRANK CASE PRESSURE AND MAKES THE ENGINE SMOKE OUT OF THE BREATHER.
NOW THAT'S ALSO GOING TO MAKE YOU SECOND GUESS YOUR ASSEMBLY PROCEDURE. HERE'S SOME QUICK TECH. THE RINGS ROTATE ON THE PISTON AS THE ENGINE RUNS AT AN AVERAGE RATE OF SIX RPM.
THAT'S CAUSED BY THE CROSS HATCH ANGLE IN THE CYLINDER. NOW A PISTON RING IS UNIQUE IN THAT IT IS A RECIPROCATING SEAL, SO IT MUST MOVE FREELY, INDEPENDENT OF THE PISTON, TO OPERATE PROPERLY. THESE ARE STOCK REPLACEMENT CAST PISTONS FROM SEALED POWER THAT ARE FOR A 40 THOUSANDTHS OVER BORE. NOW THE RING PACK IS ALSO FROM SEALED POWER AND IS A STOCK CONFIGURATION.
(PAT)>> ALMOST ALL OEM PISTONS HAVE A NOTCH IN THE TOP, WHICH FACES THE FRONT OF THE ENGINE. THE REASON BEING THE WRIST PIN BOSS IS OFFSET IN THE PISTON.
HERE'S WHY THEY DO THIS. OFFSETTING THE WRIST PIN TOWARDS THE MAJOR THRUST SIDE OF THE ENGINE KEEPS THE PISTON FROM MAKING NOISE ON COLD START UP. FACTORIES HAVE ALWAYS DONE THIS SO THE CONSUMER DOESN'T HEAR A SLIGHT CLICKING SOUND OF THE PISTON SKIRT IN LOW AMBIENT TEMPS. THE RODS ARE RIDING ON KING NONCOATED BEARINGS, AND WILL BE TORQUED TO 40 FOOT POUNDS USING EXTREME PRESSURE LUBE. NOW IT'S TIME FOR THE SOLID FLAT TAPPET BUMP STICK FROM COMP CAMS. IT'S A SINGLE PATTERN WITH 220 DEGREES OF DURATION AT 50 THOUSANDTHS LIFT AND HAS 440 THOUSANDTHS VALVE LIFT ON THE INTAKE AND EXHAUST. THE LOBE SEPARATION ANGLE IS 110 DEGREES.
(MIKE)>> ORDERED FROM SUMMIT RACING, A STOCK REPLACEMENT TIMING SET WILL MAKE THE CONNECTION BETWEEN THE CAM SHAFT AND THE CRANK. NOW THE SEVENSIXTEENTHS BOLT IS TORQUED TO 35 FOOT POUNDS. IT'S AN EASY INSTALLATION, JUST LINE UP THE TIMING MARKS AND MOVE ON. WE'LL APPLY LOCTITE HIGH TECH GASKET SEALANT ON THE FEL PRO GASKET TO HELP PREVENT LEAKS AND ALLOW IT TO STICK TO THE BLOCK AND STAY IN PLACE. FOLLOWED BY THE OIL SLINGER, WHICH LUBRICATES THE CHAIN. NOW THE COVER CAN GO ON AND IS SECURED WITH ARP FASTENERS. TO KEEP THE CRANK SNOUT IN THE INSIDE OF THE BALANCER FROM GALLING WHEN IT IS PRESSED ON, A GOOD PRACTICE IS TO APPLY LOCTITE ANTISEIZE TO THE SURFACES. IT'LL ALSO MAKE IT EASIER TO REMOVE WHEN THE TIME COMES. NOW THIS BALANCER IS FROM PIONEER AND IS AN UPGRADE COMPARED TO THE FACTORY PIECE. SEALING UP THE BOTTOM END IS A FEL PRO MULTIPIECE
OIL PAN GASKET. WE'LL SPRAY THE CORK WITH MORE HIGH TECH GASKET SEALANT AND DROP THEM ON THE PAN RAIL. SILICONE NEEDS TO BE APPLIED WHERE THE GASKET BRAKE LINES ARE TO PREVENT LEAKS. NOW THE FRONT END SEAL CAN BE LAID INTO POSITION. IT HAS LOCATORS THAT SECURE IT TO THE TIMING COVER. THE REAR END SEAL GOES ON THE OIL PAN AND IS SECURED THE SAME WAY. AND THE PAN DROPS ON AND IS SECURED WITH MORE ARP'S.
(PAT)>> WITH THE ENGINE UPRIGHT, WE CAN BRING THE NUMBER ONE PISTON TO TRUE TDC AND INSTALL A TIMING POINTER, WHICH NEEDS A LITTLE MODIFICATION TO ALIGN. SO WE'LL COVER UP THE ORIGINAL MARK. AND SINCE THIS BALANCER WILL ALWAYS BE ON THIS ENGINE, USING A ROTARY FILE, A NEW NOTCH WILL BE MADE ON IT. NOW WE MARK IT WITH A WHITE PAINT PIN
AND TDC IS SET. NOW THE PRELUBE SOLID FLAT TAPPET LIFTERS CAN BE
DROPPED INTO THEIR BORES. THEY WERE SUPPLIED WITH THE CAM KIT FROM COMP CAMS. THE CLEAN DECK SURFACE ON THE BLOCK AND HEADS PROMOTES A GOOD VALVE SEAL BETWEEN THEM AND THE HEAD GASKET. A FEL PRO PRINTOSEAL COMPOSITE IS OUR CHOICE FOR THIS SLANT SIX.
(MIKE)>> OUR VALVES ARE REGROUND AND WILL GET INSTALLED WITH ALL NEW HARDWARE. NOW DUE TO OUR AFTERMARKET CAM SHAFT, MATCHING VALVE SPRINGS ARE NECESSARY IN THE HEAD. THESE CAME WITH THE CAM KIT AND ARE DESIGNED TO WORK WITH OUR INCREASED LIFT AND DURATION. WE'LL SLICK THE VALVE STEMS UP WITH ROYAL PURPLE
ASSEMBLY LUBE BEFORE SLIDING THEM INTO THE GUIDES. NOW THE NEW SEAL CAN GO, ON AND RIGHT BEHIND IT IS THE SPRING AND RETAINER. MAKING THIS JOB EASY IS OUR GOODSON PNEUMATIC
SPRING COMPRESSOR. WITH THE MODS INSTALLED, THIS ASSEMBLY IS WRAPPED UP.
(PAT)>> OH, THERE WE GO!
(MIKE)>> THERE'S NO NEED FOR HIGH DOLLAR FASTENERS TO RETAIN THE CYLINDER HEAD ON THIS ENGINE. PRELUBED STOCK ONES WILL DO THE JOB JUST FINE. I LIKE THE LOOK OF THE BLACK HEAD ON THE RED BLOCK TOO.
IT LOOKS NICE.
(PAT)>> THEY GET TORQUED IN THREE STEPS FROM THE CENTER OUT TO 70 FOOT POUNDS. THE PUSH RODS ARE SOLID DESIGN THAT DO NOT DIRECT OIL TO THE ROCKER ARMS. THE UPPER VALVETRAIN IS OILED FROM THIS ONE ROCKER SHAFT STAND THAT PRESSURIZES THE ROCKER SHAFT WITH OIL, AND THAT SPLASH LUBRICATES THE FRICTIONAL SURFACES.
(MIKE)>> WITH THE ROCKER SHAFT TORQUED WE CAN LASH THE VALVES. NOW SINCE THE ENGINE IS COLD, THE RULE OF THUMB IS FOUR THOUSANDTHS TIGHTER THAN A HOT LASH SINCE THIS IS AN IRON BLOCK AND IRON HEAD COMBINATION. THE FINAL IS EIGHT THOUSANDTHS ON THE INTAKE, 10 THOUSANDTHS ON THE EXHAUST. A SPECTRE STAMPED STEEL CHROME VALVE COVER IS THE CROWING JEWEL TO THIS LEANING TOWER OF
NOT A LOT OF POWER.
(MIKE)>> WE'RE BACK AND HAVE JUST ENOUGH TIME TO FINISH DRESSING THIS 225 SLANT SIX UP WITH ALL OF ITS ACCESSORIES. LETTING THE ENGINE EXHALE IS A SUPER COMP HEADER WITH INCH AND FIVEEIGHTHS INCH PRIMARIES FROM HOOKER. NOW IT'S A TWO PIECE DESIGN WITH DUAL TWO AND A HALF INCH COLLECTORS. ON THE INDUCTION SIDE AN OFFENHAUSER SINGLE PLANE ALUMINUM INTAKE MANIFOLD THAT ACCEPTS A
FOUR BARREL CARBURETOR. THE MUST BE INSTALLED TOGETHER. SO HAVING TWO SETS OF HANDS IS A BIG PLUS. PUSH THIS HEADER IN AS FAR AS YOU CAN GET IT. NOW A LITTLE MODIFICATION WAS NEEDED TO THE INTAKE ITSELF SO IT TIGHTENED EVENLY WITH THE HEADER FLANGE. NOW THE MOUNTING PADS HAVE TO BE NARROWED SINCE THEY ARE THICKER AND SHARE THE SAME FASTENER. THE HEADER CAME WITH SEMI CIRCLE RETAINERS, AND WE'RE LUCKY THEY DID BECAUSE THEY'RE HARD TO FIND OTHERWISE.
(PAT)>> SUPPLYING THE GO JUICE IS AN EDELBROCK 500 CFM FOUR BARREL WITH MANUAL CHOKE AND MECHANICAL SECONDARIES. FOR COOLING A CARDONE ALUMINUM WATER PUMP. NOW WE CAN MOUNT THE HEART OF THE ENGINE. IN THIS CASE IT'S A MELLING STANDARD VOLUME PUMP. A FACTORY DISTRIBUTOR LIKE THIS USES A SET OF POINTS, BUT WE LIKE A LITTLE MORE MODERN TECHNOLOGY.
(MIKE)>> SO IT'S GETTING UPGRADED TO THIS IGNITER TWO ELECTRONIC IGNITION FROM PERTRONIX, BUT NONE OF THAT IS GOING TO HAPPEN UNTIL YOU SEE THIS ENGINE NEXT TIME.
THAT'S BECAUSE WE FOUND A HOME FOR IT IN A CLASSIC CHRYSLER THAT DESERVES A NOSTALGIA ENGINE
JUST LIKE THIS ONE. NOW WHEN THE CAR GETS HERE, WE'RE GONNA THROW IT ON THE CHASSIS DYNO AND SEE JUST HOW MUCH POWER ITS BONE STOCK 225 WILL PUT DOWN AT THE REAR TIRE. THEN WE'LL WORK OUR MAGIC AND SEE WHAT THIS SLIGHTLY MODIFIED 225 WILL DO. AND WE'RE EXPECTING SOMEWHERE IN THE 25 TO 30
PERCENT INCREASE RANGE.
(PAT)>> ACURA AND HONDA VTEC OWNERS WILL BE EXCITED TO KNOW THAT THEY CAN UPGRADE THEIR RIDE
WITH THIS TRICK SUPER TUNE UP KIT FROM ACCEL. THE IGNITION SPECIALIST HAS PUT TOGETHER THESE COMPONENTS THAT WILL NOT ONLY MAKE YOUR ENGINE PERFORM BETTER, BUT LOOK GREAT WHILE DOING IT. IT COMES WITH A HIGH OUTPUT COIL, THUNDERSPORT SPIRAL COIL WIRES, AND UNIQUE CAP AND ROTOR ASSEMBLY THAT COMES IN SEVERAL DIFFERENT TRANSLUCENT COLORS AS WELL AS THIS CLEAR ONE. SO IF YOU WANT TO STAND OUT FROM THE CROWD IN BOTH LOOKS AND PERFORMANCE, YOU CAN PICK UP ONE OF THESE
KITS AT YOUR LOCAL PERFORMANCE PARTS HOUSE
FOR AROUND $100 BUCKS.
(MIKE)>> MATCO TOOLS HAS ANOTHER HOT NEW ITEM MAKING ITS ROUNDS OUT ON THE TRUCKS. IT'S A DUAL LASER INFRARED THERMOMETER THAT CAN READY FROM 26 BELOW ALL THE WAY UP TO 1,022 DEGREES FAHRENHEIT. THE DIGITAL DISPLAY IS EASY TO READ, AND IT HAS
A 12 TO ONE DISTANCE TO SPOT RATIO. NOW IT COMES IN A MOLDED PLASTIC CASE TO KEEP IT
SAFE WITH INSTRUCTIONS AND A SET OF BATTERIES. NOW YOU CAN PICK YOURS UP FROM YOUR LOCAL DISTRIBUTOR FOR RIGHT UNDER $125 BUCKS.
(PAT)>> EDELBROCK CONTINUES TO LEAD THE WAY IN INNOVATION FOR THE GOOD OLE SMALL BLOCK CHEVY WITH THEIR NEW ECNC 185 CYLINDER HEAD. IT FEATURES A FULLY CNC'ED 64cc COMBUSTION
CHAMBER FILLED WITH STAINLESS 2020 AND 1600 VALVES. THE EXHAUST PORT IS 75cc, AND THE INTAKE PORT COMES IN AT 185cc. THEY COME FULLY ASSEMBLED WITH HYDRAULIC ROLLER VALVE SPRINGS AND THREEEIGHTHS ROCKER STUDS WITH GUIDE PLATES. THEY FIT 1986 AND OLDER INTAKE MANIFOLDS, AND EDELBROCK IT'LL MAKE AS MUCH AS 30 HORSE MORE THAN A STANDARD SET OF THEIR PERFORMER RPM HEADS. THE PRICE, RIGHT AT $980 BUCKS A PIECE. WELL THAT'S IT FOR US, WE'LL SEE YOU NEXT TIME.

THE REAR MAIN SEAL I'M PUTTING IN IS SOMETHING SPECIAL AVAILABLE FROM FAST FISH AUTO PARTS. HEMI SPECIALIST JEFF GUNTHER CREATED THIS SEAL TO FIX THE AGE OLD PROBLEM OF THE LEAKY REAR MAIN SEAL ON BIG BLOCK MOPARS. SINCE THIS SLANTY SHARES THE SAME MAIN JOURNAL SIZE AS A HEMI, IT'S A FANTASTIC UPGRADE. FOLLOW THE INSTRUCTIONS TO A "T" AND YOU'LL HAVE NO ISSUES.
FINALLY IT'S TIME TO LAY THE CRANK IN. ROYAL PURPLE MAX TOUGH LUBE IS PUT ON THE BEARINGS, AND 80 PLUS POUNDS WORTH OF IRON IS SET IN ITS PLACE. THE SEAL GETS A DAB OF RTV AND IS ROTATED SO THE PARTING LINE IS INSIDE THE BLOCK. GOING FROM THE INSIDE OUT, THE MAIN BOLTS ARE TORQUED TO 70 FOOT POUNDS.
(MIKE)>> TO FINISH UP THE CRANK INSTALL WE NEED TO PREP THE REAR MAIN SEAL RETAINER. A LITTLE BIT OF LOCTITE ON THE BOLT'S THREADS AND SOME SILICONE ON THE SIDE SEALS, IT'S READY TO GO IN.
AFTER EASING IT INTO PLACE, WE CAN LOCK IT DOWN BY TORQUING IT TO 30 FOOT POUNDS. LAST BUT CERTAINLY NOT LEAST IS THE CRANK'S END PLAY. NOW THE FACTORY RANGE WAS FRONT TWO TO SEVEN THOUSANDTHS. THIS ONE CHECKS IN AT A COMFORTABLE FIVE THOUSANDTHS.
(MIKE)>> WE'RE BACK AT IT AND OUR LEANING TOWER OF POWER IS READY FOR MORE PARTS. NOW IT'S TIME TO PREP THE PISTON AND ROD ASSEMBLIES. FIRST MAKE SURE THE DOTS ON THE RINGS ARE FACING THE TOP OF THE PISTON. SECOND, THE RING GAPS NEED TO BE CLOCKED SO THEY DO NOT ALIGN. NOW IF THOSE RINGS DO ALIGN, YOU CAN GET EXCESSIVE BLOW BY, WHICH CAUSES CRANK CASE PRESSURE AND MAKES THE ENGINE SMOKE OUT OF THE BREATHER.
NOW THAT'S ALSO GOING TO MAKE YOU SECOND GUESS YOUR ASSEMBLY PROCEDURE. HERE'S SOME QUICK TECH. THE RINGS ROTATE ON THE PISTON AS THE ENGINE RUNS AT AN AVERAGE RATE OF SIX RPM.
THAT'S CAUSED BY THE CROSS HATCH ANGLE IN THE CYLINDER. NOW A PISTON RING IS UNIQUE IN THAT IT IS A RECIPROCATING SEAL, SO IT MUST MOVE FREELY, INDEPENDENT OF THE PISTON, TO OPERATE PROPERLY. THESE ARE STOCK REPLACEMENT CAST PISTONS FROM SEALED POWER THAT ARE FOR A 40 THOUSANDTHS OVER BORE. NOW THE RING PACK IS ALSO FROM SEALED POWER AND IS A STOCK CONFIGURATION.
(PAT)>> ALMOST ALL OEM PISTONS HAVE A NOTCH IN THE TOP, WHICH FACES THE FRONT OF THE ENGINE. THE REASON BEING THE WRIST PIN BOSS IS OFFSET IN THE PISTON.
HERE'S WHY THEY DO THIS. OFFSETTING THE WRIST PIN TOWARDS THE MAJOR THRUST SIDE OF THE ENGINE KEEPS THE PISTON FROM MAKING NOISE ON COLD START UP. FACTORIES HAVE ALWAYS DONE THIS SO THE CONSUMER DOESN'T HEAR A SLIGHT CLICKING SOUND OF THE PISTON SKIRT IN LOW AMBIENT TEMPS. THE RODS ARE RIDING ON KING NONCOATED BEARINGS, AND WILL BE TORQUED TO 40 FOOT POUNDS USING EXTREME PRESSURE LUBE. NOW IT'S TIME FOR THE SOLID FLAT TAPPET BUMP STICK FROM COMP CAMS. IT'S A SINGLE PATTERN WITH 220 DEGREES OF DURATION AT 50 THOUSANDTHS LIFT AND HAS 440 THOUSANDTHS VALVE LIFT ON THE INTAKE AND EXHAUST. THE LOBE SEPARATION ANGLE IS 110 DEGREES.
(MIKE)>> ORDERED FROM SUMMIT RACING, A STOCK REPLACEMENT TIMING SET WILL MAKE THE CONNECTION BETWEEN THE CAM SHAFT AND THE CRANK. NOW THE SEVENSIXTEENTHS BOLT IS TORQUED TO 35 FOOT POUNDS. IT'S AN EASY INSTALLATION, JUST LINE UP THE TIMING MARKS AND MOVE ON. WE'LL APPLY LOCTITE HIGH TECH GASKET SEALANT ON THE FEL PRO GASKET TO HELP PREVENT LEAKS AND ALLOW IT TO STICK TO THE BLOCK AND STAY IN PLACE. FOLLOWED BY THE OIL SLINGER, WHICH LUBRICATES THE CHAIN. NOW THE COVER CAN GO ON AND IS SECURED WITH ARP FASTENERS. TO KEEP THE CRANK SNOUT IN THE INSIDE OF THE BALANCER FROM GALLING WHEN IT IS PRESSED ON, A GOOD PRACTICE IS TO APPLY LOCTITE ANTISEIZE TO THE SURFACES. IT'LL ALSO MAKE IT EASIER TO REMOVE WHEN THE TIME COMES. NOW THIS BALANCER IS FROM PIONEER AND IS AN UPGRADE COMPARED TO THE FACTORY PIECE. SEALING UP THE BOTTOM END IS A FEL PRO MULTIPIECE
OIL PAN GASKET. WE'LL SPRAY THE CORK WITH MORE HIGH TECH GASKET SEALANT AND DROP THEM ON THE PAN RAIL. SILICONE NEEDS TO BE APPLIED WHERE THE GASKET BRAKE LINES ARE TO PREVENT LEAKS. NOW THE FRONT END SEAL CAN BE LAID INTO POSITION. IT HAS LOCATORS THAT SECURE IT TO THE TIMING COVER. THE REAR END SEAL GOES ON THE OIL PAN AND IS SECURED THE SAME WAY. AND THE PAN DROPS ON AND IS SECURED WITH MORE ARP'S.
(PAT)>> WITH THE ENGINE UPRIGHT, WE CAN BRING THE NUMBER ONE PISTON TO TRUE TDC AND INSTALL A TIMING POINTER, WHICH NEEDS A LITTLE MODIFICATION TO ALIGN. SO WE'LL COVER UP THE ORIGINAL MARK. AND SINCE THIS BALANCER WILL ALWAYS BE ON THIS ENGINE, USING A ROTARY FILE, A NEW NOTCH WILL BE MADE ON IT. NOW WE MARK IT WITH A WHITE PAINT PIN
AND TDC IS SET. NOW THE PRELUBE SOLID FLAT TAPPET LIFTERS CAN BE
DROPPED INTO THEIR BORES. THEY WERE SUPPLIED WITH THE CAM KIT FROM COMP CAMS. THE CLEAN DECK SURFACE ON THE BLOCK AND HEADS PROMOTES A GOOD VALVE SEAL BETWEEN THEM AND THE HEAD GASKET. A FEL PRO PRINTOSEAL COMPOSITE IS OUR CHOICE FOR THIS SLANT SIX.
(MIKE)>> OUR VALVES ARE REGROUND AND WILL GET INSTALLED WITH ALL NEW HARDWARE. NOW DUE TO OUR AFTERMARKET CAM SHAFT, MATCHING VALVE SPRINGS ARE NECESSARY IN THE HEAD. THESE CAME WITH THE CAM KIT AND ARE DESIGNED TO WORK WITH OUR INCREASED LIFT AND DURATION. WE'LL SLICK THE VALVE STEMS UP WITH ROYAL PURPLE
ASSEMBLY LUBE BEFORE SLIDING THEM INTO THE GUIDES. NOW THE NEW SEAL CAN GO, ON AND RIGHT BEHIND IT IS THE SPRING AND RETAINER. MAKING THIS JOB EASY IS OUR GOODSON PNEUMATIC
SPRING COMPRESSOR. WITH THE MODS INSTALLED, THIS ASSEMBLY IS WRAPPED UP.
(PAT)>> OH, THERE WE GO!
(MIKE)>> THERE'S NO NEED FOR HIGH DOLLAR FASTENERS TO RETAIN THE CYLINDER HEAD ON THIS ENGINE. PRELUBED STOCK ONES WILL DO THE JOB JUST FINE. I LIKE THE LOOK OF THE BLACK HEAD ON THE RED BLOCK TOO.
IT LOOKS NICE.
(PAT)>> THEY GET TORQUED IN THREE STEPS FROM THE CENTER OUT TO 70 FOOT POUNDS. THE PUSH RODS ARE SOLID DESIGN THAT DO NOT DIRECT OIL TO THE ROCKER ARMS. THE UPPER VALVETRAIN IS OILED FROM THIS ONE ROCKER SHAFT STAND THAT PRESSURIZES THE ROCKER SHAFT WITH OIL, AND THAT SPLASH LUBRICATES THE FRICTIONAL SURFACES.
(MIKE)>> WITH THE ROCKER SHAFT TORQUED WE CAN LASH THE VALVES. NOW SINCE THE ENGINE IS COLD, THE RULE OF THUMB IS FOUR THOUSANDTHS TIGHTER THAN A HOT LASH SINCE THIS IS AN IRON BLOCK AND IRON HEAD COMBINATION. THE FINAL IS EIGHT THOUSANDTHS ON THE INTAKE, 10 THOUSANDTHS ON THE EXHAUST. A SPECTRE STAMPED STEEL CHROME VALVE COVER IS THE CROWING JEWEL TO THIS LEANING TOWER OF
NOT A LOT OF POWER.
(MIKE)>> WE'RE BACK AND HAVE JUST ENOUGH TIME TO FINISH DRESSING THIS 225 SLANT SIX UP WITH ALL OF ITS ACCESSORIES. LETTING THE ENGINE EXHALE IS A SUPER COMP HEADER WITH INCH AND FIVEEIGHTHS INCH PRIMARIES FROM HOOKER. NOW IT'S A TWO PIECE DESIGN WITH DUAL TWO AND A HALF INCH COLLECTORS. ON THE INDUCTION SIDE AN OFFENHAUSER SINGLE PLANE ALUMINUM INTAKE MANIFOLD THAT ACCEPTS A
FOUR BARREL CARBURETOR. THE MUST BE INSTALLED TOGETHER. SO HAVING TWO SETS OF HANDS IS A BIG PLUS. PUSH THIS HEADER IN AS FAR AS YOU CAN GET IT. NOW A LITTLE MODIFICATION WAS NEEDED TO THE INTAKE ITSELF SO IT TIGHTENED EVENLY WITH THE HEADER FLANGE. NOW THE MOUNTING PADS HAVE TO BE NARROWED SINCE THEY ARE THICKER AND SHARE THE SAME FASTENER. THE HEADER CAME WITH SEMI CIRCLE RETAINERS, AND WE'RE LUCKY THEY DID BECAUSE THEY'RE HARD TO FIND OTHERWISE.
(PAT)>> SUPPLYING THE GO JUICE IS AN EDELBROCK 500 CFM FOUR BARREL WITH MANUAL CHOKE AND MECHANICAL SECONDARIES. FOR COOLING A CARDONE ALUMINUM WATER PUMP. NOW WE CAN MOUNT THE HEART OF THE ENGINE. IN THIS CASE IT'S A MELLING STANDARD VOLUME PUMP. A FACTORY DISTRIBUTOR LIKE THIS USES A SET OF POINTS, BUT WE LIKE A LITTLE MORE MODERN TECHNOLOGY.
(MIKE)>> SO IT'S GETTING UPGRADED TO THIS IGNITER TWO ELECTRONIC IGNITION FROM PERTRONIX, BUT NONE OF THAT IS GOING TO HAPPEN UNTIL YOU SEE THIS ENGINE NEXT TIME.
THAT'S BECAUSE WE FOUND A HOME FOR IT IN A CLASSIC CHRYSLER THAT DESERVES A NOSTALGIA ENGINE
JUST LIKE THIS ONE. NOW WHEN THE CAR GETS HERE, WE'RE GONNA THROW IT ON THE CHASSIS DYNO AND SEE JUST HOW MUCH POWER ITS BONE STOCK 225 WILL PUT DOWN AT THE REAR TIRE. THEN WE'LL WORK OUR MAGIC AND SEE WHAT THIS SLIGHTLY MODIFIED 225 WILL DO. AND WE'RE EXPECTING SOMEWHERE IN THE 25 TO 30
PERCENT INCREASE RANGE.
(PAT)>> ACURA AND HONDA VTEC OWNERS WILL BE EXCITED TO KNOW THAT THEY CAN UPGRADE THEIR RIDE
WITH THIS TRICK SUPER TUNE UP KIT FROM ACCEL. THE IGNITION SPECIALIST HAS PUT TOGETHER THESE COMPONENTS THAT WILL NOT ONLY MAKE YOUR ENGINE PERFORM BETTER, BUT LOOK GREAT WHILE DOING IT. IT COMES WITH A HIGH OUTPUT COIL, THUNDERSPORT SPIRAL COIL WIRES, AND UNIQUE CAP AND ROTOR ASSEMBLY THAT COMES IN SEVERAL DIFFERENT TRANSLUCENT COLORS AS WELL AS THIS CLEAR ONE. SO IF YOU WANT TO STAND OUT FROM THE CROWD IN BOTH LOOKS AND PERFORMANCE, YOU CAN PICK UP ONE OF THESE
KITS AT YOUR LOCAL PERFORMANCE PARTS HOUSE
FOR AROUND $100 BUCKS.
(MIKE)>> MATCO TOOLS HAS ANOTHER HOT NEW ITEM MAKING ITS ROUNDS OUT ON THE TRUCKS. IT'S A DUAL LASER INFRARED THERMOMETER THAT CAN READY FROM 26 BELOW ALL THE WAY UP TO 1,022 DEGREES FAHRENHEIT. THE DIGITAL DISPLAY IS EASY TO READ, AND IT HAS
A 12 TO ONE DISTANCE TO SPOT RATIO. NOW IT COMES IN A MOLDED PLASTIC CASE TO KEEP IT
SAFE WITH INSTRUCTIONS AND A SET OF BATTERIES. NOW YOU CAN PICK YOURS UP FROM YOUR LOCAL DISTRIBUTOR FOR RIGHT UNDER $125 BUCKS.
(PAT)>> EDELBROCK CONTINUES TO LEAD THE WAY IN INNOVATION FOR THE GOOD OLE SMALL BLOCK CHEVY WITH THEIR NEW ECNC 185 CYLINDER HEAD. IT FEATURES A FULLY CNC'ED 64cc COMBUSTION
CHAMBER FILLED WITH STAINLESS 2020 AND 1600 VALVES. THE EXHAUST PORT IS 75cc, AND THE INTAKE PORT COMES IN AT 185cc. THEY COME FULLY ASSEMBLED WITH HYDRAULIC ROLLER VALVE SPRINGS AND THREEEIGHTHS ROCKER STUDS WITH GUIDE PLATES. THEY FIT 1986 AND OLDER INTAKE MANIFOLDS, AND EDELBROCK IT'LL MAKE AS MUCH AS 30 HORSE MORE THAN A STANDARD SET OF THEIR PERFORMER RPM HEADS. THE PRICE, RIGHT AT $980 BUCKS A PIECE. WELL THAT'S IT FOR US, WE'LL SEE YOU NEXT TIME.
