Small block rebuild

^^ Check the rear end. Lots of slant six's came with 8.25 rear ends. I've owned them. Also, the 7.25 rear end is good to easy mid 14's in a A-body. In fact, still have the 7.25 in my '74 318 Duster and it's going on 4 years of 14's. Few trips to the strip and a lot of "out of towns"... lol.
