It will be a 347 with 10:1 , with my AFR 165's, RPM 2 intake, FTI hydralic roller cam, and the rest of the bolt ons that are in my sig. The car is full weight with the exception of no spare tire, jack, AC, Air pump, and fiberglass hood.

Id say you will be trapping 110+ with a 347, also the torque is awesome with a 347, i have seen my friends car run with a 347 n/a, what his 302 ran with a 150 shot, e.t. wise anyway. the 302 still trapped higher with the nos vs the n/a stroker.
