how much hp

i am shooting for 400-450hp range so far this is what ive got:
Afr 180cc 68cc heads
xtreme energy xe274 At 0.05 230 236 0.487 0.490 lsa 110
street dominator high rise dual plane
holley 650
3000 stall
9.5-10.0:1 compression
botom end is stock 350 all new
if not what else will i need. got to keep it streetable
i just read another post about someone not liking the AFR heads very much. is there a better set with the same numbers im looking at. i know holley has a set of the 180cc 68cc heads.since all the aftermarket heads are only a few $ difference some one suggest some thing better for what i want please do so.

Are we to guess this is a Gen1 since both the LT1 and LS1 can hit that number with a whole lot less work?

Ya won't get there with those 68CC chambers. Not without a Laaaarrrrggee dome on the piston.

there is nothing advanced about this topic !!!!!!!


wont be long till your moveing along lol
