i plan on doing a 331 stroker in my car, i was wonder what heads do any of you think i should run, i plan on putting a supercharger on it running around 9lbs
don't worry bout the stock block, keep the rwhp at 450 with a custom tune and u will be fine.
Remember have the cam designed round the head and intake cfm flow among other things, the intake s/h always flow more than the heads and the heads and intake need to be port matched. Go 1 3/4" LT's.
for the shortblock go Scat 4340 crank, Probe or scat 4340 I beam liteweight rods w/ 7/16" ARP rod bolts and Probe -14.2 dish 9:1CR forged pistons, Romac ultralite damper and Fidenza alum flywheel, balanced @ 28oz imbalance. Liteweight rotating assembly spins up real fast.
