Beefed up My six, need more power to the Rear

inertia said
If you still got the 2:45 or 2:76 rear gears in there, all the carbs, cam, and headers in the world won't help till above 40 mph..

A 3:55ish gear set would be more suitable in this application, jmo

cheers

I do agree. I don't know the specs on your cam but if it's got some decent overlap it could be killing your low speed torque. But then we get back to what centerline was the cam installed at?
