I am thinking of building a 650 hp hemi for my 67 Coronet drag car. Thinking of around a 4K stall and foot brake launches. I have a 742 case 8 3/4 with MW spool 3.91 gears and 35 spline axles and 1350 joint in the car now with cal-tracs. Do you think this rear could handle the hemi?
I know put a dana in and forget-about it, but since my 8 3/4 is already in there thought I ask for opinions.

Thanks.



We blew up 3 of them last year with our mild hemi....Oh, and one drive shaft!

Hemi's eat 8-3/4 rears....The fourth one is still alive under the car so far this year, but its not stock anymore, and two weeks ago, I bent all 10 of the 3" long wheel studs on it. Now it needs the 5/8" studs...

And this is a pump gas street car with a very mild hemi that I got to run 11.1 in. We put milder gears in it last week and went from 4.30's to 3.91's and it didn't even slow it up 2-tenths. The car weighs 4010lbs with driver. Its running low 11.30's on street tires, mufflers at that weight....

Bent all ten studs??? Maybe a torque wrench would help.
