The 572's finale

We were on a mission to make some monstrous horsepower with our GM 572 crate,

other than ported and polished tads and shaft mounted rockers. This big block was pretty much all stock

but defeated enough 110 octane race fuel. We tried a couple of holly ultra dominators

and with the 1250 CFM version, the engine made 791 horsepower.

Then came the fun part, an N Os Cheeter Nitrous system first using nozzles for a 150 shot of spray

on the first nitrous pool. 970 horsepower.

We were knocking on the door of well over 1000 horses but could the bottom end handle a 250 shot of nitrous. We knew that crank and rods could.

But as it turned out the factory, a RP ROD boats were only rated at about 850 horsepower.

So we loaded up the rod and piston assemblies and took them here.

Chas

in Nashville handles machining on every kind of engine from street to strip from marine to round track.

Shackle

started the business in the mid 1990 S and now shares management duties with his son, John

well, it started out in the garage and uh

finally grew into a business and um here we are doing full machine shop service.

John is gonna handle the task of beefing up our 572 rods with new A RP 2000 bolts.

Putting the the stronger rod bolt in will is somewhat like buying insurance. It's going to be a safer rod bolt can handle more extreme pressure that that engine is going to be producing,

coated with a RP assembly loop. John installs the new stronger bolts and torques each to 75 ft pounds.

Then over at the rod honing machine, John finds the least round rod and this one is only slightly out of the range of tolerance, which is one half of 1000.

Fortunately, most of the rods are in pretty good shape and only need a little bit of touch up. This one here is a little on the tight side so we'll give it a light brush and bring it to zero.

So we got

only one bad boy. Huh?

One bad one. We'll take it, take it apart and get it fixed up and

make it like the other seven.

Pretty lucky that only one rod needs help from the resurfacing machine.

The resurface rod is now a good bit smaller in diameter,

so it needs a lot of honing to bring it back to the correct size with complete roundness.

It's a back and forth process,

but finally it's right on the money.

Well, that didn't take long. Let's go back to the shop now and make 1000 horsepower.

Now, before we stuff the rods and pistons back in the holes, we're gonna replace the bearings and they came from the high performance line at Clevite.

Now we'll go ahead and lube them up with some royal purple assembly lube

to refresh your memory. Both the street and race 572 trade engines were introduced in 2002.

We were one of the first to get the race version, which we've used with several projects over the years.

So we've been into this motor many times before

just to make sure all the parts are back in sync though. We're gonna make a first run without nitrous. Oh, it's good to hear that beast run again,

isn't it?

It's a needle loader. Here we go.

She's ready, huh? She's ready.

Here it goes. That long awaited 250 shot.

It's either shatter and scatter the parts

or have a good solid around here. I think this

boole

pole

hauler,

the time is set at 26 degrees for this first nitrous pass.

Wow, we got over a grand and we got 1000 and five horsepower.

Not bad, but there may be room for improvement. Let's try a couple more degrees.

We got 1000 8 horsepower. We broke 1000 broke 1000. Hey, man, that's good. That's good. Yeah, that's good.

Be happy. I was hoping for a little bit more, but hell,

I think

that'll be a beast. Well, this proves, I think that you could take a high performance crate, engine, massage the heads a little bit. Maybe upgrade rod boats, throw some spray at it.

Make some monstrous power for less than 20 grand. That is cool. Plus, if you think about it, our baseline was 790 we just made 1000 and eight. That's 218 horsepower more. That's pretty impressive there too. Hey, I'm happy. Yeah, me too.

Let's shut this thing down.

Hey, what's not to like about a cool classic grocery getter like this, Chevy.

You're about to see how this one delivers the goods in more ways than one

that is after the back story behind. What has to be the most beautiful baddest Biscayne on the road.

Ever wonder what kind of personal hot rods professional racers go for.

Well, when Jason Lyons not chasing points in N hr a pro stock competition

or chasing more power for the next race.

He's searching for that special project car

and his most recent search came to fruition at the 2009 Las Vegas Nationals. When's the last time you saw a 68 the game wagon? So maybe there's a reason for that. I don't know. But, uh,

but I, I'm, I'm just, uh, I'm a

muscle car lover. Anything with a big engine in it. Uh,

I just kinda, I'm drawn to that for whatever reason. I don't care what kind of car it is

after the race. Jason and crew members, Rob and Pat drove the wagon home to Mooresville, North Carolina

to begin its intense transformation

during the off season. Back at KB racing, the whole Pro stock race team pitched in to turn a 10 year project into a one year job.

We're all car guys too. So it, it's, it's part of the business where we get to. This is our relaxation. This is our fun when we do this kind of stuff.

Jason even talked to his teammate and boss Greg Anderson into helping build the engine

and equally cool. Their sponsor summit racing, jumped on board, donating most of the parts that came right out of their catalog looks just like our pro stock camp, just a little bit smaller

bottom and complete.

We got it right. Hopefully

find out shortly. We will, you know, our piston is about 5000 out of the hole

out of the hole positive. So we're gonna put a 51,000 head gasket in to get us back to 46 thousands total

debt clearance on our piston.

The trick flow heads are ready to use out of the box, but not when you're a pursuer of power like Mr Lyon here. Our motto is uh anything that's worth doing is worth overdo. So, uh so we, we probably did a little bit.

We basically just uh welded the floors up of the uh the intake runners and uh

raise the whole runner up. 100 and 50,000. We left the cross sectional area alone

and uh the head is still a 360 cc port and we also changed from a 45 degree uh valve seat to a 50 degree valve seat.

They used a shaft mounted rocker set up from Jessel to add a trick flow, single plane intake manifold, massaged by Wilson who does most of their pro stock work

before long. The big block beast was loaded up in the shop's dyno Cell

that

I do

peak torque at 4800 RPM. S 726 ft pounds

and peak horsepower at 6500 RPM. S

uh 812 horsepower

work on the chassis body and almost everything else was handled by Jim Smith

at Street Customs and restoration. He and his staff turned the massive 42 year old wagon from this

to this. It actually went together pretty quickly and uh relatively smoothly because of the fact it was an all original car. So we weren't dealing with a bunch of reproduction pieces and aftermarket fenders and doors. It, it went together actually pretty smoothly.

It's just hard to build a car when you know, it is what they call a no chip build to get it done without chipping anything. It was, it was a challenge but uh we, we did it when he came to look at it when it's all said and done sitting on the ground. He was like, you know,

that's what I envisioned in my mind. That's the car I was looking for. So

when I saw that and I saw a smile, I knew we hit a home run

and now less than a year later, Jason's Jewel is ready for its ultimate performance test.

You're on a quarter mile stretch of baseball.

Today is the day of reckoning. So it's gonna be exciting.

Imagine finding a rare unusual rust free old muscle car.

You drive it home a couple 1000 miles where you treat it to a top notch professional makeover.

The result is a beautifully restored blue 68 Biscayne wagon.

So, what's its future? A

Pampered trailer queen?

Well, there's your answer.

Pro stock racer, Jason Lyons, a wagon lover from way back

and this one is his new personal hot rod.

He and racing partner, Greg Anderson built a 557 cubic inch big lock for it.

And the whole KB racing team got involved in the engine project.

Well, of course, they're N hr A sponsors summit racing providing parts. It was supposed to be a long term project. Jason has no peace. So it turned into a short term project,

but we like to go fast. So we're all the guys in tech. We're all excited about it because they work with him on solving problems and working with his guys. It's very cool besides look at it. It's gorgeous. We'll do a burnout,

try to go on maybe half track or something. Just see what happens.

Not a bad baseline, but not a short shakedown run either. It was going fine so that I would just stay in it just to, just to make sure and, uh, you know, sh shift it short and

then it just went right, right, right on the racetrack. So, really, uh,

all in all, uh, not, not too bad. So now we're gonna tune out a little bit. We'll see if we can, uh,

either either slow it down or speed it up. It's worth noting the summer track heat is enormous. So icing down the intake is essential. Unless we want to be here into the night

at 1109 at 100 and 23 miles an hour, that's really close.

Ok. So that was wrong direction.

It's fun. It's a lot of fun and I'm, uh,

I'm having a big time

like you're back in high school on the

way.

I do. Actually, I wish I had a car that fast and that night when I was in high school. But, uh,

uh, it's a lot of fun. I, I feel like a little kid again. So, and that, that's the whole purpose of, uh, you know, building a hot rod like this. And, uh,

that's what it's all about. And, uh,

I can tell you, I'm, I'm having a large time.

There's another 100th off the last run and in Round Robin fashion, Jason comes right back to the line for more.

Unfortunately, heavy rains came after another run this time with man riding shotgun.

I'm pretty happy. Uh,

there, there's definitely more left and, uh, you know, we'll try again.

Sure he'll get there.

In the meantime, this insane Biscayne is gonna turn a lot of heads on its way to and from the hometown grocery store.

We couldn't live up to our name without our chassis

dyno or our engine

dyno.

Today we take that technology to a whole new level

and at the same time, we'll see how much we can improve the performance of this. 08 GT 500.

You've seen us use our chassis dyno

from

dyno

Jet countless times, measuring the performance gains of all kinds of upgrades. Now, while horsepower and torque are more important to us now, we've got it upgraded so we can monitor all kinds of variables that tell the whole performance pitch.

Yeah, but now check out our biggest upgrade, it's called a load absorption unit. And this thing can help you tune for drivability and overall performance but more about it in a minute

first though the usual baseline run on this Mustang,

it's got a 5.4 L engine that makes about 500 horsepower at the fly wheel.

Ok. How can we improve on 433 horsepower and 434 ft pounds of torque with a small budget?

Well, with this

super chips has been in the performance tuning business since the early eighties

and this flashback performance tuners engineered for impressive power right out of the box

in addition to reading data and offering advanced tuning options.

Ok. Now, it's asking if we want the quick tune or the advanced the advance is where you can go in and change your rev limiter, your speed limiter tire height and such.

We just want the quick tune for power

while we're waiting on this download. Let me remind you to hang on to this little cable that comes with the programmer. That way you can go into your computer and check for updates and load them up in no time.

That's it. We are newly tuned.

Now, for any reason you want to go back to your stock factory tune. It's always gonna be in here. You can get to it any time and get back to square one.

That's 30 more horses, 24 more foot pounds.

Well, Mike was mashing the gas on those runs. I was watching our run screen and we've always had these gauges but now we can monitor live things like spark advance fuel rail pressure, calculated load, math voltage irritate temperature and a whole bunch more. All thanks to this little red module that Carl

Chastain brought from dyno

Jet Cool tool there,

Joe, this tool is very cool. This is our

dyno Jet OBD two interface module. This will data log information from any 96 and newer vehicle. Basically, all I need to do is plug this into the OBD two port on the car.

Select the PS I wanna view in real time,

view them in real time and then review the information on our graph. When we're done with the run,

we can see a 5500 RPM. The car made a 30 horsepower gain. She went from 420 horsepower to 450. We can also see that boost stayed roughly around nine pounds of pressure

and we can see that air fuel went from 12.1 to 11.94.

It's a little richer but not enough to make a 30 horsepower gain. Let's try to see why.

Now let's take a look at fuel rail pressure. We can see it's a 39 P si which is what A Ford should be running at

intake air temperature only fluctuated within 10 degrees, not enough to make a 30 horsepower change. But now let's take a look at spark advance. We can see we got close to a four degree change.

It went from 15 degrees to 18.86. That's where our 30 horsepower change came from.

The

dyno rollers use the inertia to measure power. The new Eddy current box over there is a braking device. So how are most shops using it?

The Eddy current brakes gonna allow you guys to put the vehicle in real world conditions by creating vehicle, road profiles built off the frontal area and coefficient the drag of the car.

This is gonna allow you guys to create a better tune

in conjunction with the OBD two interface using this Eddy current brake. You're gonna know everything that's going on with this car before you let it off the dyno

and back out on the street.

Once we get the hang of it, we'll show you how it works on an upcoming project.

High performance and high tech, great combination. See you next time.
