So i currently have a sbc 350 and just picked up a 406sbc. I need some opinions on this motor. It will be going in a drag only car. Im wanting to be in the 450-500hp range (car to run 11's). Heres the list ive started with

Crankshaft: N4003750 Nodular Iron SBC 400 mains, 3.750" stroke
Forged Rods: I5700P SBC 5.700" press fit w/ 3/8" bolts and nuts
Pistons: (already have) Forged weisco piston #5016H4
Cam: Need opinions
Pushrods/lifters: need opinions
Intake: Use the Edelbroke preformer off of 350

Im looking at the ls1 stock heads as i can find them very cheap and will upgrade at a later time. Ill be running the street class

LS1 heads wont fit on the old SBC

is this post for real? if you don't know that LS based heads won't fit on a Gen I block, you shouldn't be building race car.

but anyway....why did you pick up a 406 when your 350 block with the crank you listed would have got you to your goals very easily?

and who in the hell puts a Performer on a 406ci??? or any real performance engine???

they do make a gen 1 block that you can put ls1 heads on. Ill assume you meant lt1 as in the old camaro/vette in the 70s.
