What's wrong with Comp Cams? I've used them for decades and they're always my 1st choice. I have a Jeep 4.0 to 4.6 stroker and chose Comp Cams for it. I haven't fired it yet, should I be scared? Educate me.


I just put a cam in my 440, I used one of Comps kits for all of the parts. Break in went fine and so far I have 20 miles on it.
