7-Foot Wide, 700 HP, 10,000-RPM Pontiac Trans Am Built In Parent’s Side Yard

If you were browsing the SEMA show this year, it is possible that you stumbled across this insane creation – a 1970 Pontiac Trans Am. The builder and owner of the car, Riley Stair, built it in his parent’s side yard in an open carport. There’s really too much to list, but here are some highlights of what’s done to this Trans Am. Check out this home-built SEMA star.

From side to side, the car measures an incredible seven feet across. The car is mostly a tube-frame chassis, and just glancing down into the engine bay, you see all sorts of craziness. The car is powered by a naturally aspirated 400ci 6.5-liter LSX V-8 built by Motor Machine out of Carmichael, California. The upgraded internals bump this car up to 700 rear wheel horsepower, and it redlines at 10,000 RPM. With the engine sitting so far back in the bay, the exhaust also makes a home in the engine bay complete with “spaghetti headers” up front. Wheels of choice are Panasport C8-16s from the ’90s, and they are wrapped with big Hoosier rubber.

Riley decided to paint the car in GM’s Ermine White, a color that ran from the mid-50s to the mid-70s. The bodywork has been done at home with the help of a bead roller, and the flares were done in just four days thanks to SEMA crunch time. Also, check out the awesome home-built cage inside!

You can watch the video from Build Biology for even more details about this crazy build – 17 minutes and worth it.
