Anyone ever put one of these in an Fbody. My dad is a huge mopar guy and wants to fab up an 8 3/4 in my formula. Should be lighter then a 9 inch and stronger then a 12 inch and fairly cheap. Also has anyone ever run 4:56 gears in a 6 speed car. How'd that work? Thanks for the info.

I have one for sale on the Motown board that I used in my car it is a very nice set up. I don't have any pics right now the car is out a chassis shop getting a new cage etc. I ran a stock chrysler posi with a richmond 4.30 gear car has been 10.86 on spray and street driven. I have no need for this rear end anymore I have ordered a fab 9 since the new motor will be putting out over 1000hp and I don't want to hurt a good 8 3/4 rearend.

Here is one pic I have taken while I was removing the roll bar rear floor of car before sending out for the new cage to be installed (Pardon the dust)

i can't remember the casting numbers but i think some 8 3/4" aren't as good as others.

Casting numbers 489 and 742 are the two you want, they use larger pinion bearings. The 741 and X castings use very small pinion bearings about the same size of 10 bolts.
