ok thanks. perhaps when you have the Ford diff out for test driving you can mention any "differential" noticed in backlash/sloppiness. I suspect the GM is better!
Subject: RE: question for Bill on V8 kit Date: Fri, 27 Apr 2012 19:50:15 -0600 From: [email protected] To: [email protected]; [email protected] I have to admit to not having driven the ford diff. We just put one in the '09, but not running yet. Probably the thing that makes them the smoothest is to stay with stock cams. The car I drove home tonight has the getrag with a standard 430 hp LS3. Much less jerky (as in not at all) vs Elvis with the cammed 480, which does some 1st gear parking lot lurchiness.

I had a rebuilt 7.5" diff in my previous V8 Monster and it seemed to have some backlash or play and I am eventually planning to go forward with another V8 Project with a more suitable and efficient power plant than the 5.0 Ford which was hard to tune, hard to cool, and gave awful MPG. (lot of that was the twinscrew superchargers fault combined with a crude Ford ECU) since FM offers two choices, the diff difference is something I was wondering about! thanks
