i think stock is 75mm but dont hold me to that, anyway just get a stock throttle body and have it ported and polished. it will easily support 385. are you looking for 385whp or fwhp? if you want 385 whp you are going to need a cam, most cams won't work with ls6 valve springs, but i think gm hot cam or asa cam will get you there. also the lingenfelter gt2-3 cam will work with those springs and give you the power you want.

you will need cam to make 385 hp.look at a Texas Speed cam pkg,consider 228r cam.you will need a tune,look at mail order tune from Frost if you don't have a tuner locally.also look into a better air cleaner lid and cold air intake set up .go to ls1howto.com for some instructions on a cam swap.
