Are these reasonable power expectations for a 408W with....

AFR 185's
1.6:1 Roller Rockers
TF Stage 2 Cam
408 Stroker at about 9.5:1
Edelbrock Victor Jr Intake
Barry Grant 750 vac secondary
MSD ignition


My buddy is about to start building his 2nd Factory Five Racing Cobra and he wants a 87 octane pump gas engine that makes around 450+ horse at the crank. It'll be backed by a TR3550 "Road Race" spec tranny.

He was talking about a built EFI 302 with a Kenne Bell. I said, first, DUH! that 302 won't run on 87 octane with a blower and 2nd, save yourself about 2 grand and do a 351W stroker and it'll run on 87while making the same kind of power. He was like yeah I didn't even think about it needing 93 octane gas.....and he knows better.
