Damn that sucks. Very sorry to hear that. Well now that you have to go to a Dana. Now you can upgrade to the 1-7/8 headers

Are you doing up a Dana or buying one done.

A local friend with a 5.50 small block 66 barracuda has his own fab shop. Does back halves, rears, cages, etc, etc
He is gonna call me within the next week or 10 days to bring my car over to his shop. Said he will have it done in 3 or 4 days.
I told him what i thought my options were, and he heard me out.
He then said he would “ fix me up” he has all kinds of stuff around.
Not sure if he is going to build me a Dana, a new chunk, use a new S60 he said he “has laying around” or exactly what....
He is going to “ sponsor” me he said. Really likes my car. Kinda been a racing mentor of mine for the last 20 odd years
I am in wonderful hands. He and his wife are great people and very successful. His wife owns a company with several hundred employees, and he tinkers in his shop, retired... doing fab work and building cars( only Mopars)

If it just broke some teeth off the R&P........ you could just put some new gears in it.

One of my friends used to have a 446 in his 69 Dart (3550lb with driver).
He did a lot of bracket racing with that thing.
Mid 10-sec car........ 8-3/4 with 4.10’s.
It would use up a set of gears in about 400 passes.

The gears I took out of my heap looked perfect from a wear standpoint. In fact I had them sold.
Until I looked closely at them......... quite a few cracks in the teeth visible to the eye.
 
Me recommending new gears for your 8.75 is like thinking my stock shafts in my 904 are going to last.....

id personally go “8 and 4 quarter” (you know... the 8.75 with the .25 upgrade) or the S60.
D60 is good... and it’s not like we’re throwing gears in all the time, but with the S I have my other ring gear already on a spool and the shim packs for the pinion in a bag. In a jamb I can swap gear pretty quick. I carry 904 shafts and my other gears on long trips or multiple day races. :)

the 4.10 chunk i had in the car started whining... a buddy had a 35 spline spooled chunk with 4.30’s he had behind his light, low 11’s stock stroke 340 before he went to a stroker B1BA deal with Dana.
He had a lot of laps on it, but it was a cheap 400 dollar compatible quick fix last season.
That is i am sure what broke. Peeled some teeth.
That is why i have ignored the button in the car except to back it up...lol.
Dumb as i am, i knew better than that
 
Oooof, sorry to hear about your 8 3/4.....I'm a little scared to say how old mine is, for fear that it will just break whilst sitting still in the garage, lol. I believe I have about 23 years on my chunk/35 spline axels/spool, but only 17 years on the 4.10 gears..... with LOTS of nitrous launches and sub 1.5 60' times (currently running 1.38-1.39).....all footbraking of course.

I am trying to save for a dana, as you are the second person I know in the past month that has broken an 8 3/4.
 
Knock on wood I’m surprised my son never broke a set. He did try to change out the gears every 3-4 years. The last set had three years in them and the car ran as fast as 10.11@3200 pounds. A buddy of ours begged him for his pumpkin (4.10 gears) right after my son hurt his engine and he told him they were due to change out but he wanted them. He’s on his third year with them in his big block duster that runs 9.80’s.

my blue Duster years ago had an eddie 416 deal than ran almost like current car. Over a winter i swapped on a W5 top end, and kept everything else. Flat tappet, etc
Went 10.38 with it off the trailer at 3400 pounds.
Made three hits, next morning took it up to Stanton( mid mi motorplex) to bracket race it.
Broke the 8.75 at the hit, first pass.
You have been exceedingly lucky. I knew this was on borrowed time at mid 1.40’s 60 foot at 3320. I was right, took about 30/35 passes. 35 spline spool, etc, but stock case, not the upgraded one available now..although i suspect the ring gear, which a slightly better case probably wouldn't have mattered
 
Some guys are lucky with their 8 3/4 rears, I wasn't one of them. Mine was a pretty fresh set of Richmond 4.30's, probably 35 passes behind my 340, it ran 7.24 @ 3240# with 1.51 60', so it wasn't a hard leaver. I built the 408 and it ran 6.57 with a 1.38 60' at 3260# on the first pass it hooked. The second pass it hooked it shucked some teeth off the ring gear.

The next day I had the car on jack stands with the rear end out making plans for a mini tub and a S60. The 8 3/4 was rebuilt and sold complete to a buddy of mine that lived in Ohio at the time and the money was applied to the new rear end. I now have a stronger rear end than I'll ever need.

I do wish I had gone with a 9" though for the simple fact I could have a chunk set up with 4.10 for driving and a set of 4.88 or 5.13's for when I want to bracket race.

Looks like you opponent was holding some numbers or he's a fender racer (same dial).

think he just miss dialed the car. He didnt know we were paired till the last moment and didnt change his dial when he saw we were racing.
Buddy said i spun a little at the hit..tires are shot..
Had them on since long before Bowling Green, and made 24 hits just that weekend alone..lol

When i was going 7.20s i was lucky to be in the 1.5anything. Most of mine were low 1.6 . I wish mine "wasn't a hard leaver" like yours.

Money pits aren't they.

There is a local guy (heads up guy) who doesn't bracket race much. When he does he diales what his opponent dials then puts a fender on them and sits there, he's pretty good at it too.

that can be a tough way to go if you are not better on the tree, the other guy is holding and on the brakes, or if you don't 100% trust the car.
I have done that before too..in street tire shootout stuff when i was much faster...with VERY mixed results..lol
 
I have some 430s [strange] street usage on them. If interested. To get back up and running. Tapered pinion.
