I have a Comp Cams 252S.
think the profile's near the same as EB's 261 or his RV cam, can't remember which.

anyway, point is, the low to midrange torque increasing cams are the way to go. some guys put those HP increasing cams on, but they don't make power until up over 4500rpm-5000rpm -- how usable is that to most people?
