1981 Grand Prix GBody build
Heres a quick post of my current build...its a 1981 Pontiac Grand Prix with a 383ci supercharged, intercooled, and nitrous. It has Spoon upper and lower control arm front and rear, ATS spindles, wilwood brakes, Hydoboost, Fab 9 rear end with brace house a Strange center..455 gears, Detroit locker, 35spline axles..I was be running a 4L80E TCI Superstreetfighter trans(2.75 first gear ratio,1.57 second, then1.1 and .75). I am running with a Weiand 177 with about 12Psi(spinning it kinda fast..hence the giant intercooler, using a AFCO heat exchanger meant for a Ford 500 and a Mez water pump. Decided to go with the smaller blower because is mainly a street car and smaller blowers produce more boost at slower RPM, plus a single card simplifies things a little
