i was lookin online at the comp cams...they are $520.00 for the Stage 3 Comp cams..they come with spring valves and followers right?
how much horsepower out of that?
what else do u need to do to get that like computer wise?

I'm pretty sure they come with springs and followers, your best bet is gonna be to call Comp and find out for sure. Personally I would go for a tune after the install simply because new cams have the potential to change the A/F ratio very drastically and that's not always a good thing. At the very least disconnect the battery and let it reset before driving it anywhere. As for horsepower, I would guess about 40 or so to the ground. When timed and tuned right, cams are a great mod.
