Ok I think im in the right forum. Ive got an 86 Z28 im building. The motor is a 385ci about 450-480hp on motor, 700r4 trans, 4.11 gears, eibach drag launch spring, lakewood drag 70/30 struts, lakewood drag 50/50 shocks, South Side machine sub-frame connectors and lift bars, lakewood LCA's, with slicks what do you think i'll run on the motor and with a 100-150 shot of spray?

 

I'd say mid to high 11's on the motor depending on how much the car weighs and traction. With a 150 shot you should be in the high 10's or very low 11's.
