Whats the difference in the Comp Cams you find on Americanmuscle.com? Both at $590 and both are same "extremem energy" brand. only difference is one is stage 1 and one is stage 2. Anyone know the difference?

intake/exhaust duration are different. Stage 2 is more aggressive then stage one. With a stage 2 cam you also need to buy valve springs and retainers, where in a stage 1 you can reuse the stock valve springs.

PTV clearance will be very tight with the stage 2's.

Is there a reason you're focusing on comp cams over some more well liked 2v cam brands? ie Hi-Tech or Crushman

the different durations in each stage basically decides were your power band is moved. In general the the higher the stage the higher your power band will be.

what do you mean by more liked? There is nothign wrong with comp cam and they are excellent cams....

So the overall consensus is Stage 1?

My vote is for the same exact cams as 0949er....Comp Cam Stage 2's XE 270AH

You really need to disregard the whole "stage" thing for a minute. The limiting factor on the stock PI heads is how much ptv clearance you have.

Bottom line...if you're staying with the stock PI heads, and don't plan on doing a blower in the near future, i'd highly recommend something like CMS stage 1's or MHS stage 2's. The Comp stage 1's should work as well, but they wouldn't be my first choice in the stock n/a application.

I did a ton of research in this area before buying my MHS stage 2's, and am glad i did.

+1, its a fairly well documented fact that Comp's grind isnt as good as some of its competitors. For the same money, better gains will be had.
