If he wants to lose some hp I got a good cam for himnow, if you would like a cheap cam to start with. I can hook you up with a stock 4.2L cam. Looking at about 10hp or so. Some extra tq. And a little heavier exhuast tone. Id let it go pretty darn cheap.
Then next, I do have a lump cam, i am going to have someone check its condition and see if its reuseable, if so ill be selling it as well. But no promises on that one.
