Well ive been looking around for some more go fast parts for my what was going to be STS on stock build but im think of buyign the comp cams FAST intake and tb(90mm). With FI will they help make HP? If they do about how much will they gain?

youd be better off with a LS6 intake and ported TB, theyre proven to a 1000hp, and would have some cash to spare,

Spend that money on a good Fi cam or some 317's to lower the compression ratio. longrange4u had a baby cam and 317's w/ his STS CETA and hit 607 hp @ 9 PSI. (Stock bottom end at that time)

where coudl i get these "317" heads at? cuz ill def grab them. and i was thinking of getting a Cam but i dont wanna pull the motor... if i pulled the motor ill just get forged internals but i def dont wanna pull anythign out. just looking for bolt ons.is a cam swap doable with motor getting pulled?

no doubt

you can get a decent set of 317's from some one on here or look for LS1 parts on ebay, i think i saw a set for like 300 or something. and the LS6 w/ ported TB is proven and will save you a ton of $$$ over the FAST set up

317 is the casting number on the low compression 6.0 liter truck heads you can get them used (sometimes new) in the Sale section for 300- 400 bucks. TRT I think sells a new set w/ patroit duel valve springs (good for .650 lift) for alittle over $600

i just picked up some low mileage 317's for $225. and you dont have to pull the motor to put a cam in. like stated above go to ls1howto.com and bring patience and tools
