5111 here is the link to Modular Madness. http://www.modularmadness.com/ They have been building mod motors since 96. They are probably going to tell you the same thing I am telling yall. Thats what they told me. And I'm blown. There are much more cost effective mods than long tubes. I will agree that if you want the very last HP out of your car LTs will help more than hurt but if I had to choose between Cams or LTs which would you choose.
