The car is an 86 Grand Prix. The engine is a 400 Pontiac with forged rods and pistons, solid roller cam, 325 CFM SD Performance CNC ported E-heads and EFI. I put an 8.5 inch GN rear in it with an Eaton posi and 3.73 gears. I have a built TH400 that is still not installed, I have been driving around with a TH200R4 and the 231 engine, but the trans is worn out now so not much driving this last summer. I put 4 wheel discs on, better rear control arms, sway bars and springs. Next is to finish the engine and go to the next level on the suspension and get some modern tires and wheels. It sports 15" Weld Prostars right now.
