Re: 1972 307 cam selection... HELP!

I agree with the 3.73 swap. If you do that you won't have to touch your engine. I had a 3.07 rear in my '69 Suburban with a crate 350 and 2004r OD trans and the high rear gear made the transmission overheat when it was locked up. Swapping in the 3.73 made a world of difference. Swapping that rear to 3.73 would be top priority for me....
