Finally swapping cams
Looking at the whole package...How confident your pistons are really at 9.5:1? How good are the X heads? Stock, or ported? Any flow numbers? I would lean towards either the Comp or the MP .509(just make sure the cam gets degreed properly...) IMO, the lunati might be a little small, where the MP might be a little too much for a "9.5" engine that really is 9:1 when it's measured and figured. The Comp will give you good cylinder pressure. 3.91s with a 29" tire isnt much gear. I think you'd go faster with a set of 4.30s in there and that same setup you have now. That being said, maybe the Lunati IS a good idea...lol.
