It goes both ways as back in the 60's many guys ran torque flight autos behind their GM and Ford cars as it was the only transmission worth a darn for many years.

9" ford, whether you like them or not, are popular under all brands of race only cars. Easier to get parts for, and if you have an issue you can find someone at the track to help you with loaner parts. If you use something else less popular then you loose some of those potential benefits. I normally prefer to keep it all under the same brand, but it's not hard to see why so many people go with the 9" in a race car application.

Gotcha

Dave, there is nothing Mopar in my Strange S-60, all aftermarket just like a large percentage of the 9" rears you see at the racetrack. The Dana's aren't Mopar either, they were just used in them just like they were un other brands. If I were doing an original car that came with a Dana, that's what I'd put in it.

I'm sure that Mopar did not use Dana 60 in any of the early (pre 1968) factory race cars
that being said I use, recommend and swear by using Dana 60 in all my race cars that won't live with a 8 3/4

And splicing heavier parts in is normal.

My point was that using a phord 9" is no more plug and play than using a Dana 60 since very few guys are going out and getting an original 60 at this point.

But it is worth noting that there are Mopar guys that do not want phord or shivvy parts on their Mopar. THEY are also doing what they want! Or maybe you disagree with that?

If someone uses a phord 9" in their car and like it.............fine. The ONLY real point was that it is NOT plug and play. No more than a truck Dana 60 is. Whether that Dana came from a Dodge truck or a phord truck.

But is it not true that there are Mopar racers that DO NOT want clearly identifiable OE phord or shivvy parts in their car? I certainly know some. You don't? That doesn't mean that there is anything wrong with it, only that it is a notable fact.

I don't think I read anywhere in this thread where anyone said a 9" was plug and play. I'm sure that there plenty of racers who keep their cars all Mopar.

My Strange S-60 is not an OE part and never was, just like the aftermarket 9" rears were never OE in fords.

By your reasoning an aftermarket rod that is a chevy size but used in a Mopar or ford is a chevy part? Have you ever used an aftermarket stroker crank? Rods with 2.100 or 2" journals and .927" pins? Do you use only OE pistons in your builds? Heads and intakes?

I've been a Mopar guy since the late 60's when I was a kid and it's funny to see guys claim an OE supplier like Dana/Splicer as Mopar when the truth is that they supplied parts for just about all manufacturers.

Read the posts. I wasn't the one who brought up 'plug and play'. I only responded to that statement.

As to all the rest...................NO, that is NOT my reasoning. You misconstrue/misunderstand my position. Either accidentally or deliberately. Which seems to happen quite often with some on here..........................

Take care Dave, I hope you have a great Christmas.

What suspension? If springs in stock location I think your fine. If it's ladder/4-link and the housing is not braced, I think you will bend the housing.

I went 6.00 in the 1/8 with one, but it broke. Took out the tranny case, driveshaft, yoke. They are good. Just not the best option for fast stuff.

I will use caltrac mono leaf and bars.

If you are foot braking, throw some aftermarket axles and a crush sleeve eliminator in it and let it eat. We had one live 250+ trans brake dead hooking on drag radial launches behind a 600hp small block in a 3200lb Duster. Cass at Doctor Diff can hook you up or I can build a 489 and send it to you.

PS: we run Redline Heavy Shockproof lube. https://www.redlineoil.com/heavy-shockproof.

I have been running 8 3/4s for years I currently run 11.50s with high 1.40 60 fts foot braking on a drag radial with Cal Tracs and mono leafs . My Dart weighs 3225 with me in the car . The car has been as fast as 10.40 with a 1.40 60 ft. I have had very few problems with running an 8 3/4 in over 40 years any problems have just been due to wear , I run a Mark Williams spool and axles and have both a 742 housing and a 489 depending on gear ratio I am running and the rear housing is braced. They are a pretty tough rear ! I broke a driveshaft last year and the only rear damage was to the u joint bolts ( I have since added a Moroso u joint retainer instead of u joint bolts ) I also run the Red Line shock proof rear oil . I am pretty satisfied running 11.50s as thats the class I run but if I did step up the horsepower I would go with a direct bolt in made to fit my application Strange Dana .
