I'm curious what your combo is if you will share. That's a big goal. Not saying it can't happen or being negative at all, just curious how you're going about it

The current combo , if i'm lucky, will see 9.8 9.9 at 136 mph. LOL
I'm thinking of building a rear once and that would mean I would never see anything faster than low 8.

So let's say 3200 lbs A body mono springs with T brake.
Looking at low 8s.
What should I be looking for?

Oh my a nine inch in your mopar!! That's worse then a powerglide!

the new [feb. '17] issue of hot rod magazine did a comprehensive story on the 9", page #88. might be an interesting read for you guys if interested.

Not a popular thought........but a Dana is a truck rear end. I don't care if it did come in some passenger cars, it was designed for a truck. I don't want a heavy truck rear end under my race car. Plus the 9" has all the aftermarket support in the world.

The question is a nodular case or aluminum?
spool or wavetrac posi?
wavetrac limits me to 35 spline.

In your case I would buy a complete alum center from Strange. There are several options on which case and pinion support. This is not a pro-mod, so you don't need the pro-mod center.

All the Dana "fan boys" want to rail on how expensive a "good" 9" is, so they always quote the price of the MOST expensive setup for the Ford they can find and compare it to a junkyard find Dana.

OK, so lets look at some REAL world pricing. The complete center you need from Strange is about $1400. That's with a spool, standard gear and 1350 yoke. A posi or pro gear is an upgrade price. So now you need axles, brakes and a housing. Axles brakes are the same for any rear, so it boils down to what you will have in housing. You can brace a junkyard housing or buy a fancy sheetmetal and prices will vary greatly..........But how about lets just get in the Strange catalog and see what we see.

The S60 ready to bolt in your Mopar with a 35 spline spool, standard gear and Pro axles is $2100.

They also make a Mopar ready sheetmetal Ford housing with spring pads. That housing with afore mentioned 35 spline alum center, spool, standard gear and 35 spline axles is $2500...........Say what? That can't be right. $400 difference, I read on Moparts that it costs twice as much to build a Ford........LOL!!!

Now, how do I know this pray tell? That would be because I have a catalog, because I am a Strange dealer........LOL!!!

Jesus, they used the 9 inch in trucks too.

The only thing the 9 has going for it is gears. I know several Stock guys who ditched the 9 to get a 12 bolt and went faster with the 12 bolt.

Not everyone is Pro Mod.

"spool 40 spline gun drill. Aluminum case🖒🖒..we did a back to back test with a 8.3/4.vs9 in a 69 dart that the 8.75 ring and pinion would only last 100 pass before they would fracture💣💣... the 9-inch was only 400 slower.... the pinion on a 9 inch is much lower enabling the car to Be set up lower... 9in all day any day"

In your test, do you mean .04, or .004?

Everybody talks about the 9" in-efficiency, and I read where 3 rear types were compared. But in that comparison an atmospheric change could have easily negated any and all differences.

Has anybody seen/done a torque in/torque out test? I just find it hard to believe this rear is not efficient. I run two of them.

The ONLY thing is gears?......LOL!!! Ok, whatever you say. A Dana is heavy, the gear selection sucks, serviceability sucks and in a hard leaving car, you can NOT brace the housing to keep it from bending. Can't be done without adding a jungle gym of tubing bracing that may or may not help, but certainly adds to the weight.

Nope, not everything is a pro mod..........but everything damn sure ain't a stocker either. This guy is talking about a low 8 sec 3200lb A-body goal. That's gonna be a pretty damn powerful rig right there. Whether he does it or not is on no importance, that's the goal, so you build for the goal. So in my opinion Dana and damn sure 12 bolt.......never enters the discussion.
