go big or go home....make your ls1 into a 402 get a set of ported ls1 heads and a FAST 92/92 and you can tell everyone it's stock with a cam

It'll probably be cheaper to just buy a short block....

do the 383 with a forged rotating assembly to handle more nos.

save your money build a 383. Make sure you use a good dish and the nos will love it

**alex a** · 07-28-2009, 01:09 PM

like what size dish would work good

**99transamC/FIA** · 07-28-2009, 02:59 PM

the dish will depend on a whole bunch of shit, bore size,stroke,head cc,gasket size,piston ring land.
keep the motor at 10:1 and it will live forever on a 200 shot(with the right tune).
with a 383 i think its -10cc with a 72 cc head.
