Shortest Rear end
Alright, So what is the Shortest rear end drum to drum that ford makes, or what is the shortest rear end in vehicle history that will be able to handle HP from a 302. No more HP than 320 and no more FT Lbs than 320? If you know, then you can help me. Thanks

The 8 inch drop out used in 1974/80 V6 Pinto wagons and 1975/78 Mustang II's with either a V6 or a 302 would get my vote as the shortest. These two cars used rear leaf springs.
The 8" was introduced in 1962, and was the usual rear axle used with: 221/260/289/302/351W's thru 1979, and Ford 6's (mostly 200/250's, and the 2.8L V6) from 1967 through 1980 (some cars with 200 engines used in 1964/66 had 8's also).
8 inchers resemble 9 inchers at first glance. It has a similar removable carrier (pumpkin).
8 inchers were not installed in F Series trucks.

I wouldn't use the 8inch. Not extremely strong and has little aftermarket. What are you putting it under? The Ford 8.8 is strong than both the 8inch and the Dana 44. The 9inch is a little stronger. If you are going to tub it out you are probably looking at some custom work reguardless; as in narrowing the axle. Out of probably all the axles the Ford 9 inch will be the cheapest to do because of the massive aftermarket for it.

1966-1977 Bronco rear ends are very narrow........ they are 9" rear ends LOTS of aftermarket support and dirt cheap.
I can't remember what year they started using the big bearings on the axle. It might have been 1975. The big bearings are more desirable if you intend to use the stronger 31 or 35 spline axles available through the aftermarket. If you stick to the horsepower and torque levels you said then any one of these axles will work fine.
Like the last post said, avoid the 8" simply because of the lack of aftermarket support.
Good Luck,
Kent

You can get plenty of 8" stuff here, as well as 9" and custom housings etc.

1968/77 Bronco's with a rear axle load rate of 3300 lb. use the 3 5/32" O.D. large wheel bearing.
