as long as you have all bolt ons like longtube headers, catback, pulley..etc..etc.. you can hit 400rwhp cam only.. you will definitely make 430-450 with heads/cam..

you will get alot of answers on this.. people will ask your budget, goals (which you already said)..etc. your best bet is just to look at the sponsors on here and see what kind of power people are making with their setups.

Might want to check out the 'Dynamometer Results & Comparisons' section for rwhp results to help you decide on a setup.

AFR or TRICK FLOW heads. I made 463hp on a stock ci ls1 with afr 205 heads and the combo was not maxed out.

vengeance racing head/cam kit with the biggest cam will make 450rwhp

I would say heads are the most important part of the equation and getting a cam to compliment them would net you some great numbers. Do a search on trickflow, and afr heads and see what they came up with.

some ported 243s and a custom cam .
