The Buick we currently race in Drag Radial, had a 10 bolt under it when we bought it. The car had run 5.50s with small blocks when we bought it and our big block made it a 5.20 car right off the bat. We ran the 10 bolt until we broke it (which wasn't long). The point was, the car "evolved" from a streeter to a low 5 sec car and the 10 bolt was "good enough" to a point.......then it wasn't.........so in Dom's case, moving from an 8.75 TO an 8.8 under his car........well he may as well light that money on fire, because it will accomplish the same thing.
Monte
Just curious Monte, what rear is in that Buick?
Chromoly 9" sheetmetal Ford housing, with 40 spline gun drilled axles, alum Mark Williams center, with a 3.70 Pro gear and a billet 1350 yoke with a solid joint............expensive? yeah I guess, but high power, hard hooking radial cars will break EVERYTHING. Radial cars are harder on drive line parts by FAR than slick tire cars. That said, we have NEVER broken a single part in the rear...........Several radial guys I know this year were twisting and breaking 40 spline axles. That's how hard these cars can be on parts.
Monte
If thats the case, then move up to a Dana 70, 10.5" ring gear, 35 spline axles, 3.5 tubes with .5 wall thickness, looks like a 60 but on steroids inside! 1401 ujoints and a bunch of ratio's up to 7.17 to 1 Tim
Oh I love getting on here. Twisting 40 spline axles and should go back to 35 spline and add 150 lbs in the process. That is exactly what they should do. I think you should call all the big chassis shops and get them all on board with the dana 70 movement also. You better buy up all the parts they are going to be flying off the shelf.
heck I am heading to the junk yard today to see if I can find a dump truck rear to put in mine
Make sure you get the 2 speed axel, that will help your little SB

,looking to buy a new rear-end in the next week or 2, my factory 8 3/4 may not be up to the 535 stroker 6 pak,cope built 727 tranny, and the slicks, this is in my 70 runner,with the stroker expected to make 650 hp and 6?? torque, want to add a rear that will not fail me, as this is all new and i will being put together next month, thoughts were to buy a DANA (to stick with mopar)car will not be tubbed but inner wheel wells massaged for bigger meats. So in short a good read post
just a tip, Dana is not mopar. they came in just about all trucks. mopar used them because they knew the 83/4 wouldn't handle the big hemi's and 440s
Mopar knew some of you guys would set pinion angle wrong

A good spot to find them is in old FORD trucks. It will make a great mopar rear nice and heavy.

Forget that wimpy Dana 70, go for AAM GM corporate 14 bolt!

Are you talking the 3/4 ton chebby 14 bolt? Its about 20% weaker than the 70 and 35% less than a Dana 80. Rock crawlers bust them all the time....Tim

I know of lots of low 5s cars running 8.8s. Stock ring gear bolts suck.
I don't think it's a matter of who goes fast on an 8.8. it's a matter of if he's going to upgrade is that the best choice. I don't think it is, he would be better off doing it right the first time.
Looks like I`ll be gettin WHITEDART`s 9" after the M.A.T.S. unless it blows up or I find something sooner........ Time to step up................
Thump......you mean to tell me your giving up the 8 3/4 I thought we were the only 2 that would carry the 8 3/4 banner for life.....Lol

I would get a jy dana 70, 40 spline axles and put ford ends on with explorer or crown vic brakes. 10.5 ring gear and no heaver than the 60....and it comes with .5 thick tubes. You could build this for about $900 if you get a deal on a housing with the gears you want.
I got my 60 for $75, it was 600 to narrow and shafts from Dutchman. Pick your locker/posi unit and gears, you may get lucky and get what you want from the yard.... Brakes were $80 for the explorer discs I got a 3.55 r&p for $55, real Dana, so with a little work you can get a real nice setup fairly affordable...that will be indestructible. Tim

I know a few who have built 60`s from scratch but I have no desire and am not fond of the look. I like backbraced rears under a car, less wt. and since Ferds are my second favorite cars, a 9" it is.

I've seen a lot more nine inch race type third members,using all non Ford components, being fixed at the NHRA National races by the traveling rear end professional guys than any Mopar type rear ends being fixed or swapped out To each thier own I remember when Jack Chrisman conned Jim Dunn and Joe Reath into being the guinney pig for his R&D on switching from the Olds, Pontiac and Mopar 8 3/4 rear ends in the old funny cars and top fuel cars to the nine inch Fords In todays world thier are no OEM Ford parts in any of the decent after market performing nine inch type rear ends, not even the housings I'm sure thier are reasons for most racers using them, not me I don't make enough power to break what I run now BTW, I can't afford them high dollar race parts like the race type Ford nine inch or 9.5 inch race rear ends anyways My 1940 Ford tudor street rod will have a Lincoln Versias 9 inch rear end in it with all the recommended good parts like a nodular third member and good aftermarkey front pinion support and maybe even a back brace, if Dom will pay for that part

Well, not indestructible, but it will take quite a beating ! I ran a 4.10 geared stock Dana with a clutch type posi, shimmed so the clutch packs were locked solid. Wulla! instant cheap spool! That and a pair of spring perches, and axle ends to weld on and you are ready to go. The drive shafts might inter change as well or need a cross over joint. If the clearance is a little tight to the tranny a few shims behind the spring hangers take care of that. Dom, I doubt I changed your mind, but posted this for those who might need a poor mans rear end swap! Hope you find exactly what you want!
