Default COG drive help needed
I need to set up my procharger with a cog drive. Has anyone here done that with a 496 based block? I have stock serp and my charger is extended past that. So I need cog drive for my blower wiht the right offset and crank drive that will bolt up.

Any help would be appreciated.

Advisement from Arizona Speed and Marine. if i want to step up to 10-12lbs. There have been some recent advances in belts and drives so i have bought a new gates rpm belt and pulleys to push up to 7-8lbs from barely 2.9

I was running an M-5, I think the crank pulley was 7 and I know the blower pulley was 4.5.
