Im buildin a new motor for my 87 iroc and was just wonderin if anybody had a rough estimate of possible hp and a decent qtr time assuming a good launch and decent hook up

.40 350 4bolt block
scat light weight crank
5.7 rods
KB dome pistons 12:1+
comp XR286R roller cam
crower lifters
scorpion roller rocker arms
world products sportsman II heads. 200cc intake runners 64cc combustion chamber
single plane high rise intake
barry grant 750 carb
longtube headers
3" duals w/ H pipe and cut outs

its goin in a completely gutted iroc with subframe connectors, 4.11 gears, 10" wide street radials and a th350 with a 3k stall

 

im going to say probably near 450hp on race gas and an easy high 11 second quarter

 

excellent i would def be happy with anything over 400 and in the 12's
thanks
