I have always been told to leave the stock cam in my Super M for "stock" class pulling.

I run a tractor dyno service and that stock cam runs out around 1900 rpm. After that the torque #s fall off fast, so rpm doesn't help.

We had mine at 72hp at 1710 rpm with 198 ft lbs torqe.

With a heavy governor spring it pulled 2700 rpm at 90 hp but 155 ft lbs torqe.

We have since brought the rpm done to with in the 10% rule 1710 again and it's making a few more hp with the torqe at 210.

This motor has 150 psi cylinder presure.

I do have the 450 L.P intake on it with a 450 gas head.
