    We just finished the install on a '05 Yukon, 5.3. We installed an LS6 cam and springs, front mount intercooler, Gt-67 STS, and 8psi.

    I'd say 438/446 was pretty good, especially with 24" wheels.

    The front mount we used we had custom made with rear facing openings. It made for a very clean install. There was a dramatic difference in the temps from one tank to the other. So far the intercoolers are working great!!

    I'd love to see more pictures of the intercooler install if you have them. What are the dimensions of the intercooler?

    Those are sweet #'s for 8psi! Is the LS6 cam ideal for a forced induction truck?

    To me, the LS6 cam is a good option because of the grind and the $$$.
    You can find take out LS6 cam, springs, and push rods for less than the cam alone in most cases. Its all according to what you want. If you want a little lope, then you need more than the LS6 as it is on a 118.5lsa.
    We are starting a new car soon, a '02 Trans Am, and it will have a Lingenfelter GT-7 cam;
    208/230 .554.546 121 with #317 casting 6.0 head front mount intercooler, 42lb inj, STS turbo with some custom work done. I am thinking the numbers will be even more impressive. Looking for around 500rwhp at 7psi we hope.
