diff oil
I was told by the LHS that I needed to add more gears in my diff because I was running a 247 engine. My buddy wasn't to sure what oils I should use in the diffs. He took a guess that I should use 3000 in the front and rear. I was wondering what you guys are running. By the way I'm glad he told to beef up my trans because both the front and rear gears were starting to chip teeth. I'm sure it would have been real soon I'd be rebuilding a blown trans.
