Some 360 engine improvements
Even if you were to get a sure grip you'd need a 3.91 and a 3500 convertor to justify that cam you have. But since we're on the subject of cams. That's a lot of cam for any compression you may be getting. That's even at 9:1. Which you may very well have. A lower compression piston would most likely have a dish in it so I'm not real sure on the compression. I therefore won't guess at it.
