Need some info on the profesional products intakes I am looking into purchasing one of the professional products intakes to put on the new engine combo Im getting. It is basicly a forged bottom end 347 ls1 with stage 2 heads. Does any one know the difference between the ls2 and the ls1 version of these intakes? Can the Ls2 version be used on an ls1? Is it a dirrect bolt on? I would also like some opinions on the intakes. I know they will get hotter than the ls6 and other composite intakes. How do you guys that run them like them? Any one have any horse power numbers that prove the ls6 is better? I know the fast 90 is the way to go but I am not going to spend that much on an intake.

This is one of the main threads around for it. It's older, but it becomes somewhat recent over the length of the read.
