I'm aware they are not rated at the same tappet lift but just for interest.
Lets look at a comparison of the torque curves or "area under a curve".

The ever popular Crower 60919 cam:

304 /316 ( or what ever seat duration they use these days )
231 / 240 @ .050
.470 / .470 lift
112 LSA / 106 ICL

A very popular UltraDyne Pontiac cam years ago:

288 / 296
231 / 239 .@ . 050
.485 / .507 lift
110 LSA / 104 ICL


.

Steve,
I have file for the Crower 60919 which when I calculate duration from events is
290/300
231/240
.470/.470
112 LSA/ 108 ICL

It is from a few years ago and I don't remember where those number came from. Does anyone have a cam card for the Crower 60919 that they can post
