I would go with the Comp Cams Xe-258, 264, or 270 which is what i have. According to Michael Yount (AKA CAR GOD) " CompCams Xtreme Energy line of cams are the only ones worth buying off the shelf in my opinion. They are far superior to most other bump sticks out there. You see, one of the most important specs about a cam you can't get much info on - that's the lobe design. How quickly the ramp rates open and close the valves makes a HUGE difference in performance. It's what allows a MUCH milder cam from CompCams make the same peak power as an E cam, with much better bottom end and drivability. If I were you, I'd save a little more money, even if it takes longer, and get a custom, or go with an XE264 - XE270 if you want something a little stouter." So if you have the money go with comp, i did and couldnt be happier the motor pulls great.
