yup (that's the cam i suggested - i'm using it in my mild 440 build)....personally, the rough idle i never found to be all that great. on a racecar, fine, but on a street car it sounds ridiculous and you won't make power till 2500 or more RPMs.

i chose the XE 268 because, using camquest it was the best cam for my application (highest HP and TQ (compromise on torque, but not by much), it fit into my powerband (from 1500-5800 i believe are the specs), and i didn't want to change my converter. comp claims a slightly rough idle - idk if that's true or not. if so, fine, but if not it's not a big deal. if you get on youtube, there is a vid of a 71 GTO big block with a XE 268...it think it sounds healthy, not an over-cammed starving for air sound.
