Finally done tomorrow. Of course had setbacks. Needed new brake back plates, yoke issue, then drive turned out to be crap. New drive shaft ready tomorrow. So now it's a 9", 31 spline, 11" new drums, posi, 3.50 gears and new 3" drive shaft. Good bye 8 inch 2.79.
Should be awesome.
8" fords are still very good. Especially if you have the 67+ unit with the cross braced ## casting, instead of the one with the Flat == casting supports in the case front.
They are plenty strong, can be fitted with a trak-lock diff and have all the same advantages as a 9". I have know some vintage mustang guys who prefer them for a little less rolling resistance.
..But with 2.79 gears, it would need to be upgraded to sell for much more than just core value.
Yeah if you are making ludicrous power going all the way to plaid then 9" is the way to go. Not sure I'll ever make enough where an 8.8" can't get it done tho...
Yeah went with a posi 9. Just wasn't sure if I could get any money for the old 8".
Chevy runs deep, don't step in Chevy.
