The 60240 is not a "steep ramp" cam, like the CC XE and Voodoo series cams. The Crower ads say this cam works best with 9.5:1 CR.

One way to get the effects of steep ramp cam, without the increase in lift, is to use an 068 clone, such as a Melling SPC-7, and Rhoads lifters. When puttering around, under 3000 rpm, you'll have less duration and lift. Then passed 3500 or so, the Rhoads will restore full cam lift and dur.

Yes, I know Jim Hand didn't recommend Rhoads with a cam that small. But, I'm talkin about a specific app here. The purpose is to come up with a low lift cam, for a low comp engine, that will increase performance slightly, without changing valve springs. This combo might work.
I put an 068 with Rhoads, in a low buck, hi comp 400, stock 13" converter, and TJ won the biggest race of the year with it at the Prescott, Ark track, in '77. No, it wasn't the best possible cam/lifter/converter combo, but it ran smooth and consistent enuff to win a big bracket race.
