Anything can fail, if you break a 60, go to a 70.....bearing sizes are the same, just a larger ring gear...pinion offset is the same as a 60 too.

Look under every PS car and tell us what you find. I've haven't seen a dana under one since the late 70's,but maybe they're missing the boat

I think it's like a lot of things in racing. Back when the parts were stock based the Dana 60 reigned king but with aftermarket parts whatever is popular get's modified until it works.

You won't find a ford 9 inch either. LOL

We're all going about it wrong. An 8.75 is the best rear ever. It's just that no one ever sets them up correctly.

Maybe ---- IDK.

I will say look under Dave Dudeks car running in the F.A.S.T class and that's what he runs. He had a Dana under it when purchased but sold it and went to the 8 3/4.


I run a Dana 60 running low 9's at 3450 lbs with no issues.

There are always priorities. Is durability more important, like a Dana 60, or the ability to fine-tune gear ratios for varying car weights for different classes and/or changing weather conditions and/or altitude with removable center sections?

EXACTLY. The 9 won that war decades ago because the guys who actually change axle ratios (and transmission ratios are changed nearly every run) like Pro Stock and Comp needed gear ratios that were every close in ratio. No one wanted to change D60 gears between rounds, so the 9 got the nod.

I don't remember the year but Pro Stock was squealing for a 4.00 ratio. They finally got it, and IIRC, after a year or two, that ratio became obsolete.

The average racer who tells me he changes his axle ratio at the track to tune for conditions is either a rare bird, or he's a liar. It just isn't done.

I will say I worked with a die hard braket race with a pocket full of money who kept several gear boxes in the trailer, all with different low gear sets. He would change a transmission to get the car better on the starting line if he thought he needed it. Then someone pointed out to him that the 2 step could be altered to almost the same affect.

I don't care what kind of piece of junk you get an old housing out of at the junk yard. It can't be made as strong or as useful as this one. Now, you may not need a unit like this, but the technology and aftermarket support trickles down even to bracket cars. Some folks will take advantage of it. Some will insist on being nostalgic. Nothing wrong with either one and nothing wrong with a 60 in an old Mopar.

I think that was the point Pittsburghracer was making.

What is called a 9 inch Ford today has zero in common with a 9 inch Ford, except the dimensions.

The lowly 8.75 and the D60 have some aftermarket pieces, it's nothing compared to what the aftermarket made up for the 9.

I've seen well tuned low 8 second stick cars run on almost stock D60's and not fail if you did maintainence on them.

Take a peek at these choices.

8.75" it is. None of these point for or against the 60 and 9 are better or worse for my setup. I don't run at tracks with different altitudes, I don't need 15 different gear sets. So I'm gonna narrow what I have and move on to other projects.

I still say they're 9's. Because you can pull a center out of an old ford and bolt it into the best housing out there. Sure you need axles,but you need them for anything.

Ratio changes aren't bad on a 60 if you keep the whole setup together. I have all my 60 gear sets where they're just pull out one and bolt in another. Ultimately cheaper than swapping entire 9 centers. Almost as fast as the 9 too, but not quite. A gear set, a spool, a setup kit with bearings, and done, no case to buy. Bout a grand cheaper per ratio

My next build I’m going all out and making it as lite as possible. Starting with a 7 1/4 rearend and upgrading it with unobtainium 4 bolt 3/8 aluminum stud axles. I’m going to flycut the ring and pinion thinkness and make up the thickness difference with Old Milwaukee beer cans. I’m going to save more weight and drag by leaving the rear cover off so I can spray the ring and pinion down with Pam cooking spray before each pass. Looking for some new bests in 2019

Stir that pot until it boils

can i watch ?

Only if you bring the beer and the Ben-Gay. And YOU have to apply the Ben-Gay.

ok on the beer, but i don't have any ben-gay. however, i DO have some chapstick .........

Don't stop there. Take the seats out, and sit over the rear end like a sling shot dragster lol.

Lol. Let’s not spill all the beans in one post. I got some top secret ideas brewing. I did get a great deal on some ghost carpet. It’s so lite it’s invisible
