8 3/4 and a 4spd

[James L Miller]

Well, as Emily Litella used to say, "Never Mind".

I'll probably use the 8-3/4" in my Dart with the 273 but will have a 904TF to cushion the blow.

By the time you do all the 8 3/4 fixes you will realize you coulda had a Dana. But by all means put an 8 3/4 in it. If you want to clean out your 8 3/4 parts supply. Always enough money to do it over but never enough money to do it right.

Dana, set it and forget it.

Gotta agree on the Dana 60. I don`t race a MoPar, but I do have a low 10, high 9 second Ford bracket car that I have been racing with a 4 speed for 17 years, with a Dana 60.From 1988 thru 1999, I ran the same car with an automatic and transbrake, using a 9" with 33 spline spool & axles.
When I switched the car over to the 4 speed Jerico, I decided my existing 9 inch was not enough, and after some researching, it was actually cheaper to sell my old 9" and build a Dana 60. The Dana has beem absolutely bulletproof for 17 years of 6000 plus RPM clutch dumps.
From what I understand about 8 3/4s is that with the lower gear ratios, the teeth on the ring gear get really short, and tend to break. I know several MoPar racers that spent a lot of time and money using, breaking, and repairing their 8 3/4s, before biting the bullet and either doing a Dana 60 or a 9" Ford (when rules allow), and I can`t recall any of them that went with a Dana not saying that they wish they would have done it years earlier. If you have a bunch of 8 3/4" stuff, I would sell it and use that money towards the Dana.
