DP rear axle assembly

[Jeff Teuton]

Nobody has any flawed thinking, but from NHRA, that is what is accepted. The 9" was specific to the V10 car and now also to the 426 car. NHRA has not accepted the 'any corporate' yet for the 9" in other cars. I was just presenting what I have from NHRA after a racer complained to me about the subject and I inquired. I would hate to see one of my fellow Stock racers show up and be turned away especially at Indy because of this item. It's a whole lot easier to address before you leave to go. Pretty simple.

I believe Mike has this completely correct.

Call it what you want, or what year you want, but the part number is there.

I realize Jeff's point but NHRA needs to get this right....whats good for the goose, is good for the gander. (my Dad would have said.)

Hell, the 8 3/4 is a 9" housing anyway! And I'm sure theres no advantage either way other that life.

A good lawyer 's letter (where's Cambria when we need him) would certainly straighten this out fast.

I hear what you are saying, but Jeff is right. The NHRA, to this point, looks at the new (FX) cars differently. They really do need to publish a clarification.

It was my understanding that all the "NEW" cars (Ford, Mopar and Chev) get to run the 9" Ford with either the cast iron or ALUMINUM case................

The old rule about replacing a Factory rear end with another Factory rear end that was listed in the Factory parts list is not allowable at present.

Strange had a Aluminum case for the 9" listed in the Ford parts list and it was accepted by NHRA for about 20 years, now the only cars that can run the aforementioned case are only cars that were available from the Factory with the Aluminium case.

So let me see if I can get this straight....As of now I can't run an Aluminum case in my Pre 2008 Stocker (9") because it was not available from the Factory, but a Post 2008 Non-FORD car can???

Yeah, makes perfect sense too me.

I am not changing my r/e case for Indy.

Luv ya Jeff!!

I completely agree with MPR, but would like to add one clarification as I understand it:
The new cars (CJ DP COPO) fit into the "inclusion" rule at the beginning of the Stock rulebook correct?
Just because it was permitted on an "inclusion" car does not mean that it will be permitted on a non inclusion car.
For example: you cannot put a S9 COPO rear axle housing in your 1969 Camaro A/SA, nor can you put an aluminum center section in your 1968 Mustang.

See you at the races,

The 2009 and 2010 DP's were never allowed a 9" rear. The 2011 512 was as it was standard, and the specs for the 2011 426 car have it as standard. Doesn't apply to Fords, Chevys, Hudsons, Kiaser-Fraser, Fiats, Volvos,Lexuses,and several others. It does, however, apply to the 37 Hupmobile with the aluminum Gen III Hemi. This is not Swamp Science. And RJ, nobody cares what you do, well maybe some other Texans. I mean really, if you don't like this, then show up with the 9", tell the tech person "Look under my car. I have a 9" Ford type rear axle assembly. That's ok Huh???" The 38 Hudson Fastback is ok but only in red. Geeeeeee. Try to help someone drowning and they want to tell you how to swim.

Mr Jeff, you can lead a horse to water but some will just not drink!! No matter how thirsty they are???

Hey Jeff, sorry about my post I apoligize. Just venting about not being able to run the aluminum case and all the Non-Ford New cars can.

Reading back through all the posts it looks like its a real mess. I thought all the DP's got the 9" Ford. Hope it all works out for the Mopar camp....maybe NHRA will compensate and take some HP off .
