generally speaking, stock 243's, stock ls6 intake/tb, cam, exhaust will get you at least 410 rwhp. if you have a pretty agressive cam that number can be as high as 430-440 rwhp. with a FAST intake and ported 243's 460-470 is not unheard of with the right work.

however there are some inherent issues that come with more hp/tq.

hit up the regional section and find a good machine shop to discuss price with. i can tell you that your basic port and mill would not be too expensive and paired with the right cam you can easily attain 440-450 rwhp and have a good even mid range. remember when doing a motor average hp and tq is just as important as peak.

some of the best cams on the market right now:

and if you don't see one that tickles your fancy just call/e-mail Geoff with your build specs and he can meet your needs exactly.
