Question

Hi folks, me again...

Is it true that a 1969 8.2" 10-bolt will only accept up to 3.30 gears? I was hoping to use at least 3.55/3.73's. I think I saw an ad somewhere for gear sets for 8.2" rears but can't find it now.

Thanks!

There is not a different carrier for 355s I bought a set to replace 3.08s worked fine. Summit sells them at about the best price around.

Thanks guys..... I knew it was in one of my catalogs!
Did y'all do anything to beef the rearend up? I mean besides having it rebuilt/tuned up at a shop? I want to use the same axles if they're in good shape.

When you do this don't use any bearings made in China. They are JUNK. I also don't like the Raytek kits. I sell a kit, along with other suppliers, that has Timken bearings, adjustable shims, pinion seal, ring gear bolts, pinion nut, gasket, crush spacer and gear marking compound for $89. As far as gears, you need a 3 series differential for a 3.55/3.73 gear unless you use the special thick gear made for the 2 series diff. The 3.08 fits a 3 series so if you have a 3.08 now you have the 3 series diff. Other than after market axles, there isn't a lot you can do to make the 8.2 stronger for the street. Be carefull when you buy some of the cheap gears. Sometimes it's better to spend the money for the better parts.

Big Gear Head,
If an 8.2 rearend is setup with 3.55's, the way you suggested above, what is the maximum amount of HP/Torque that it could be expected to survive behind, in your opinion?
Thanks,
Rich

Thanks Big Gear Head,
I'll remember you when it comes time to rebuild it. No 'Made In China'!

It's got 2.73's in it now. Will it be a 2 or 3 series carrier in a '69 rearend?

I don't plan on building a massive monster burn-out machine so I'm not too worried about it breaking. Just trying to save some money from having to buy a whole new third member right now. If it breaks... I'll cough up the $1500 for a new one.

Rich253 has a great question... I'm very curious myself.

Thanks!

As far as how much it can handle, I can't realy say. I built one for my late friend Wayne Daniel a few years ago for his '69 with a 383 and a Muncie 4 speed. I was doing some tuning on it and took it for a drive and while I was out I broke the Muncie. The rear end held up fine. I built a Super T-10 for the car and the rear end still lives today. Wayne sold the car to another friend of mine who has made several hard passes in it and the rear end still lives. Some times they live and some times they don't. Wheel hop will kill some of the very best rear ends very quickly. I broke 7 ring gear bolts out of my SS454 '72 Chevelle 12 bolt and broke a axle in my '69 RS/SS396 Camaro 9" from wheel hop. As for your 2.73, you have a 2 series unit. You will either have to replace it with a 3 series or buy a gear set with the thick ring gear. I don't recomend using a ring gear spacer.

BGH,

Thanks... that's what I needed to know. I have the opportunity to buy an 8.5" 10-bolt for $200 but I guess I'll put that cash towards mine instead.
