No reason just picked the 041 out of the air as its so widely used. I guess what I am asking is if I am running a 236/244 flat hydralic magnum profile lobes from comp cams lift with 1.65 is about .580. If I went to a XR288 from comp cams very simlar duration number 236/242 with about the same lift I think .600 with 1.65's would I see any improvements ? would it be a tenth or more ???
Has anyone did a dyno or track comparasons of any Hyd Cams to Hyd Rollers of similar durations in a Pontiac engine ?????
Just looking for hard Data here is all.
