I need a new motor in my car. I'm going to put a 402 (LS2) but want to know about the top end build up. Now should I go to a LS7 style head intake combo? How much of a HP difference would there be? Do I need new headers, thought the head angle changed? Sorry I'm very new to the LS7's

Or maybe a better question how do I get 550RWHP with a 402? I like the temperment of the car now with the 224 112 cam in it, I'd like to keep it near that level of drivabilty.
Thanks
Jay

Don't think your going to have any problem making 550 with a 402 and some decent heads.

Give me an example for heads and cam? Will my current 78mm fast be OK and then switch to a 90/90 setup later for a little more power?

To find many examples do a search on 402. To me the ls7 stuff is way over priced for what you get. If nothing else you could go with the L92 top end and call it a day. Don't have any numbers for you, so I would just try a search. Its working now.
