Im being harassed for wanting a Dana 60 in the Cuda.

and just switching from drum to disc probably saved 40lbs or so.

Front yes, rear NO WAY! 10 LBS maybe!

This Blown alcohol hemi Pro Mod car also runs a DANA without any problems

the dana is a great rear for the money but it has it's limits. the aftermarket 9-9.5s are race pieces not some truck rear. as you said better selection on everything gears etc.

---

9" is a pure race rear end nowadays, there's many advantages. That's why they cost more, look under any serious race car and you'll see 9" rear ends.

I don't have to justify anything I say, greg.

If your gonna race a 600 hp car, then you don't need a serious race rear end then. How's that?

Quote:

It's a 10.0 car. Put a Dana in it and be done.

LOL...you have to justify it if you want anyone to believe it.


All serious cars run a 9"? I hardly think so...explain why the Mark Williams catalog is full of rear ends above and beyond any 9". Just walk around any pit and you'll see the fastest cars using zero 9" rears.

The 9" Ford rear is like the SB Chevy - guys use them because they are sheep.

If the 9" rear were an album, it would be 'Thriller' - proof that popular doesn't even come close to being best.

If the 9" is so great, why does Strange offer a 12 bolt center section that drops in place of the Ford guts? One reason alone - to get the pinion higher and save HP.

9" and 9.5 , is the rear end of choice for 98% of pro stock ,promod ,outlaw 10.5 and top sportsman cars .

You guys must know something that they don't.

Tony, were you there? did you see the race? C'mon, you asked what proof there was now your bashing the car. How do you know he didn't beat him because Tedder broke, or for that matter maybe he killed him by 8 car lengths..... You asked

youhave to learn when people are joking I am not bashing the car nor the source. why was a pro mod racing DT heck why not a top fuel

Kinda surprised nobody has brought up the "other" Mopar diff. I think there is a 9 second Cordoba running with a 9 1/4" diff. Definitely stronger than the 8 3/4. Takes Dana 60 size clutch discs. Bone yards are full of them - came in lots of Cordoba's and pick-ups.

---

That brown '77 I just got rid of had a Sure Grip 9-1/4" in it and I gave $2fiddy for the whole car.

If a 9 is so great why did Ford only use it in trucks no larger than 1/2 ton? When they went to a 3/4 ton....they used a Dana 60.

Chrysler's use of the Dana in no way diminished the 8-3/4. As with most aspect of their cars, Chrysler over-engineered things back then, and then some.

Let's not forget Chrysler was doing something Ford was not - offering a 5 year 50,000 mile warranty on pretty much everything. If you had to hold the bag for a 19 year old kid with a stick shifted 440-6 Road Runner, would you use a 9" Ford or a Dana?

The nodular iron 9", and 31 spline axles, you mention were used in very few cars. Another good thing about Mopar, unlike Ford of Chevy, was they used the good stuff in everything, not just for the elite few.

The factory Ford 9" iron, nodular or not, was and is weak in the pinion 'nose' bearing area. Nothing to be proud of.

And for being a purist, the last place I'm going to apologize for that is on a BB called Moparts.

You "purists" kill me. You guys do realize that DANA corporation, was in no way shape or form, a part of Chrysler. It was and is, an aftermarket company, that Chrysler and all the other brands, bought rear ends from. Chrysler was smart enough to realize that their "best" diff, the 8.75, could not hack it behind their most powerful cars, so they had to outsource a diff.....Now I am not a Ford lover, or anything like that, but i hate when misinformation gets spewed around everywhere and taken for the truth.......That said..... Factory HiPo Fords, such as Cobra-Jet Mustangs, Torinos and other top of the line stuff, came from the FACTORY, with 9" rears, with "Nodular Iron" center sections, 31 spline, hardened axles and "Detroit Locker" posi units. You would be hard pressed to find a better and more durable "Factory" HiPo diff anywhere, under any car. My dad had a record holding SS/GA, six pack Challenger in the 70s. We went to the track with 3 spare 8.75 center sections, every race. When he tired of breaking those, we got a complete rear from a Cobra-Jet Mustang, out of a junkyard, complete with factory 4.10 gears. Installed a $200 Phallanx alum pinion support, on that 100% factory original Ford rear and NEVER broke that center section or the factory axles. Matter of fact, that same factory Ford center section and that same pinion support was under my GTX the whole time I ran it and I still have it to this day...So when all our so called "experts" start spewing rubbish about those weak, factory Ford rears, I know better. Sure, the days of finding a factory 9" with a locker and Nodualr center in a wrecking yard are likely over, so are they over for finding a factory HiPo Dana in a yard. Yes, you can spend as much as you want on aftermarket 9", but I see guys on here bragging about their 1700-1900 dollar danas. I can build Fords that will take the same power, for that money all day. The difference becomes, that you can't spend "enough" on a Dana to make it last in a max HP application, because there are simply no parts to do it with. A Pro-Mod or even a Top-Sportsman car, with "real" power, will shell a Dana in just a few passes and there is NOTHING you can do to stop it.

Each diff has it's place and everyone is welcome to suggest and defend their choice...just get the freaking facts straight before you start shooting your mouth off.

Monte, you're a smart guy and I respect your opinion, but you're the one speading some bs here. Just run down to the local junkyard and pick up a factory CJ 9"? LOL, they must park those right next to the Hurst Hemi cars in the yard .

I saw factory, non CJ 9"'s(which is all there really was) get blown up all of the time on the street. I believe the 8.75 was a stronger rear than a 9".

I do agree that the aftermarket 9" is the only way to go in a high hp (1000hp+) car. Simplicity of gear changes and the availability of high end trick parts for the 9" make it the obvious choice.

That being said, if I need a rear for my 10 second b body I'll head down to the junkyard, find a Dana and have a rear that will handle all I will give it and not have to take out a second mortgage to buy a 9" that will be as strong and last as long.

You're mileage may vary

I actually referred to that part in my post, if you had bothered to read all of it. No, you likely wont find a nodular center 9" in a wrecking yard these days, just like you won't find a HiPo Dana. You can find a truck Dana, that needs a ton of work on the housing. And actually, "Nodular" center sections not only came in Cobra Jet cars, they also came in trucks and vans, along with 31 spline axles. At one time, when you could actually still find parts in wrecking yards. I had collected over a dozen Nodular centers from various yards and only one came from an actual Cobra Jet car. Still have two.

Now which 8.75 are you talking about?? That scrawny POS, that came under A bodies, or the one that came under six pack cars. I believe I will take the Cobra Jet rear everytime over the mighty A body 8.75. Who quoted that Mopar put their best under everything????? May want to rethink that comment. This is always the issue. The "purists" always compare the best Mopar has to offer, to the worst others have to offer. I am as much a Mopar guy as anybody and people that know me, have met me, and have seen my collection of cars around here know that....but I am also a realist, respect all brands and if somebody has something better, I am not afraid to say it.

Just like I said, use the rear you want, they both have their place...but don't compare the best one has to offer against the worst another has to offer and then proclaim "all their factory parts are junk and ours are the best"...that is the misinformation I speak of

Monte

Monte, I read your whole post and I have met you and know you're a Mopar guy, which is why I said I respect your opinion, something you seem to have a hard time doing in return. You complain about unfair comparisons, yet want to compare a 741 case out of a /6 Valiant to a CJ rear

The reality is that it takes a lot more money to make a 9" live behind a moderate amount of hp than it does a Dana. I've narrowed truck Dana's and used the factory R&Ps behind 600hp+ bracket cars without any troubles. You simply can't do that with a 9".

Also other than narrowing them for $150 not sure what all of this housing work is you speak of?

As for the purist thing, I'm the farthest thing from a purist there is. My all motor car will have a fabbed 9" housing and a all out big bearing pinion pig, not a Dana

Funny. The ONLY place you'll see this pro Dana arguement is on Mopar sites. Go to a nondenominational race site and start this arguement. You won't last one page. As has been stated many times, Dana is not now nor has ever been a part of Chrysler. I don't understand the undying allegiance of some.

---

For me the Dana was part of the package that was some of the best Mopar factory Muscle cars.
I don't know of any other brand using the Dana? As far as the OP if the Dana will get the job done, then that would be my choice.

Since we are still talking about "stock" rearends, I will take a run of the mill, "scrawny POS" 8 3/4" rear over a run-of-the-mill, super scrawny 9" any day of the week.

I will also take the "best" stock Dana 60, over the best stock Ford 9" rear.

Exactly Cass, that was my point as well.

WOW, you guys only see what you want to see. That comment was in reference to another poster, NOT HEMIROID, that suggested Mopar put their best in EVERY car. Obviously you can't compare a SCJ 9" to the weak a$$ A body 8.75, just like you can't compare a standard 9" to a HiPo Dana or 8.75. The whole point here, was you have to compare apples to apples and not make sweeping generalizations, that "Mopars rule"(excuse me, DANAS rule) and everybody elses parts suck.

Hemiroid, the only part of that reply that was directed at you, was that the good Ford parts COULD be found in vehicles other than SCJ cars and at one time, were fairly easy to find, same as other HiPo parts from all the brands.

I got nothing against DANA rears, actually have a vehicle with one in it....my 1 ton truck...

Some of us remember when a few SS/AA hemi cars had 12-bolts in them, as the thought was back then they take less HP to turn than anything else at the time. Would hate to hear what those purists would have said then!!!

So, let's see: a guy wants to know who can contribute to his choosing which rear in a 3200# low 10 sec street strip car, right? Then the argument starts over which was stronger in OEM form and what/why the fuel cars and pro mods have.

the reasons are many starting with:
they build from scratch with unlimited budgets.
there's not a single bolt or nut from a factory rear.
they need to swap centers at the drop of a dime between rounds sometimes mandates using a pumkins style.
strength factory vs factory unit hands down the Dana

That doesn't look like a Ford 9" to me. It must not be for a serious race car.

Quote:

huh how many people go climbing under your car tosee what rear end you run

---

Quote:

I don't race anything. I mainly build street/strip rearends.

My point is, application is everything. A 9.5" rear is not the best choice for a street/strip car OR a top fuel dragster.

If you want to build a streetable 9" rear, you are stuck with tiny bearings a tiny pinion shaft and as far as I know, only 1 choice for a 35 spline traction differential (Detroit Locker).

On the other hand, a Dana 60 has a 9 3/4" ring gear, big pinion shaft, big bearings, and ALL traction differentials are available in 35 spline. In addition, it costs LESS to build, robs less HP and weighs about the same as a comparable 9" rear. These work very well in heavy, torquey street/strip cars.

I don't consider a 9" or a Dana 60 to be to be a true "drag race rear". For higher end drag racing applications, I recommend skipping BOTH in favor of 9.5" (and larger) dedicated drag rears.

Boils down to this for me...I am NOT going to run a freaking truck rear end, in my hot street car, or race car. Lying on my back setting up a center section might be something I HAVE to do in my truck, but not my car. If an 8.75 won't get it done, I will go straight to the 9", don't care if it cost 100 times more than a DANA, because I am NOT going to lie on my back and set up gears....And before we hear about the DANA and "forget it" and "they don't break", just save that for someone who does not know better. ALL hot rod parts break eventually.

Expecially since Strange and Moser that I know of, have reproduced them for our muscle cars. I have one under my 71 street car.

My first race rear end back in 1990 was a N case 9". Since then it has been all aftermarket 9" parts.
