How fast have you been with a stock 8 3/4. 60 feet and et. Weight/Hp/tire size Just want to know when I will break my 8 3/4 Looking for a 9" or Dana,but they are hard to find here. I wonder if my 68 B-body Dana will fit my 1980 F-body that has stock frame rail and no modifications to the wheel wells. I will run 275 Micky T's drag radial. Let the bashing begin

I will assume you will back brace it... I was running mid 9s with a totally stock center... had just over 600 passes on it when the cap broke.. thats when I changed over to a alum center... on the stock one I was 2400# with 620 hp, 1.23 60', 13.5 X 31 slicks.. if you were to put load bolts on the back to touch the caps it helps alot

Yes it is back braced, but still original axels and pumpkin with a 3.91 gear and clutch type limited slip. It will be exciting to see how it will work, I think twisting the axels are what will happen first. Thanks

I have run 10.70's at 3700 lbs with an all stock 8-3/4. I know I am pushing my luck and want to go with a Dana some time when I can afford it. I use a Dynamic 9.5 street/strip converter as my car does not launch real hard but hard enough for me which I am glad as it does not seem to be to hard on the rear. But I only race a few times a year. Ron

My 100% stock 8 3/4 went best of 1.50 60ft in a 3700lb car. I took the axles out and they were all twisted up. Also, I tried (well accidentally tried) to leave REAL hard on it the last time out. Sheared the pinion off, but the stock axles survived. IMG_20130823_200437_896-1 by wright2305, on Flickr

My experience was the differential itself broke, side gears sheared. Mine now is backbraced and has a locker in it with Dr.Diff axles. So far so good.

I've been 5.80's in the 1/8 with 1.29 60ft with stock axles and sure grip before it twisted the housing. Now it's got a new one that's back braced with moser axles and spool with billet caps.

It is relatively easy to build a Dana 60, because all you have to do is to narrow the axle tubes to fit your application, and they are straight, no curves. Moser, Strange and others have the housing ends you need. You just have to decide what brakes to use. I built the latest one from a Jeep J20 rear axle that was 40 years old. It came from a wrecking yard with a 4.10 gear on a PowerLock carrier with 35 spline axles and tapered Timken bearings, 12" drum brakes, 5 on 5.5" bolt pattern that will easily fit my '87 D100. The Dana had been rebuilt (new bearings, clutches & brakes) when I got it for $400.00. I put another $400.00 into it having 1 tube shortened and 1 axle shortened and resplined. Your experience may differ, but I am pleased
