Has anyone dynoed an engine with Bob Karakashian's aka Mr Six Pack's cam, how does it compare to the factory cam, will it make more hp and torque? Many people say, it's making more power (by butt dyno), but has anyone had their engine on a dyno with that cam?


I'm just having a 383-4 resto project going on and would like to try something else than the MP Magnum replacement cam.

The specs of the Bob's cam seem to be top secret, have not found yet any measured information. Only testimonials how great it works, but how great it really works?

Those who have tested it on a dyno, please give some HP or TQ figures how big improvement you have gained.
