I think he was looking for the 41, but regardless, that cam sucks. What is it, a flat tappet cam? (<-sarcasm) Anybody in this day and age running a respectable aluminum head and intake should be looking for a roller cam with .550 lift or better. More lift, less duration, you end up with the same "area under the curve", which means good performance with good drivability. It's how the LS guys do it, they're all running HR cams with gobs of lift. Some of the stock LS cams actually have more lift than that cam listed.
