ok so i decided that i was going to go with 5.3 heads and a torquer v.3 cam. but last night i was at work looking through a summit catalog and saw that trick flow had a h\c pack that made 515 hp and i did the math a the tricks would cost me around 600 more than the 5.3s after every thing else was bought (lifters? rockers?clutch? etc.) so what i want to know is the hp going to be that big of a diff. so which is going to make more power.

prc 5.3 stage 2.5 220cc and 2.02\1.575 valves
with tsp torquer v.3 231\234 .643/.598 with111 lsa

or

tfs 215cc intake runners 64cc combustion chamber 2.040/1.575 valves and 80 cc exh.
heads with tfs cam 228/230 .585/.585

both setups would use HS 1.7:1 rockers and a weiand lsx intake(if it ever comes out) or a fast 90/90

wondering if its worth extra 600 or if i should just use the 600 bucks to pick up a zex nitrous system

thanks

i was sorta in the same boat with you, i could have bought a 2600 dollar set of heads but went with a cheaper set and am going to make up the horsepower difference (if any) with nitrous
