Very rarely will a cam lobe affect compression unless the cyl is being washed with fuel.
I'd suspect a burnt / corroded valve or seat or broken valve spring, or stuck rings, before a bad cam.
If it's rings dump rislone in it and drive it, they may free up.
Valve springs can be changed on the car.
Before you go digging too deep be sure the ignition is firing correctly on that cyl as an ign miss can wash the cyl down with fuel and lower compression.
The 396/402 was one of the best v-8's chevy built.
