Last one to post in this thread wins!

been learning on the difference in rear ends Mine is an 8 3/4 the housing I got in 3:23 is 741 witch is made for a slant 6 but was also used in the early 426 hemis.
Not going to the races with it just want something I can drive long distance.
As far as I know the only difference was in the pinion something about a step or tapperd pinion. Google it
