It's been awhile since I've been on with you guys and I am glad to be back.

Does anyone know a good place to get a 12 bolt rear end either new or used to replace my standard 10 bolt factory original?

Would it be worth it to upgrade my 10 bolt to a posi 4:11 (I'd like to keep my RPM's down to 4k max at 75 mph) rear end? I'm pushing about 475 ponies with a totally rebuilt 327 with all the goodies. If updating the existing is a better idea, what manufacture and vendor site is best for these parts?

I have also updated my Tranny to a Turbo 350 with a B&M slap shifter if that helps. Thanks...

If you are interested in a new Moser 12 bolt send me an email. biggearhead@bellsouth.net

I was just gonna say to contact you Freddie.

I think Moser is the way to go.

Mickey's bar and grill......it's down on 3rd.

Good place to pick up a replacement rear end?

Church ice cream social:yes:
Grocery store;)
Department store
Good Sumaritan to a woman along side the road:thumbsup:
Art museum:o
Outside the front door of a Ladies Night Only event at a bar:D

HA! If you're a Redneck - family reunion......LOL:beers:

Couldn't resist, I'd ask bgh, He apparently has treated other members here quite fairly as I read.

I just installed a MOser and Im very happy with the quality and strenght!
I also got mine shortend at no additional cost.

Yeah but can those other rear ends handle the torque without slapping you.

Also, I have not heard from you whether it is better to replace with a larger rear (12 bolt) or to simply upgrade the current 10 bolt housing.

I'm thinking that using the existing housing might be more cost affective, while maintaining the stock look but, I don't want to put money into a 10 bolt only to blow it up.

Could a 375 HP 327 with a 350 Turbo, really blow a built up 10 bolt if I put good quality parts in it? I'm also thinking of the down shift into 1st when the tires lock up a bit. I imagine that when I change my rear gears that this will happen even more since I am currently stock.

No, all high maintenance as with any, just some more than others.

Some require to be touched all the time.
Some require a kick to get started, and maybe to keep running.
Some require nothing at all as it can handle whatever is doled out and remain quiet.
Some require to nothing at all as they can be so strong, they break something else.

I had a 8.2 in my first 67 at the track. After 9 years, approx 300 runs per season, it stayed together. ET at 3000 lbs started at 14.50 and went to 12.50 over time with a 29X10 slick. The last hurrah split the carrier. The Th350 used broke a couple times before the axle went.

Are you talking about the women or the 10 bolt versus 12 bolt? :beers:

I don't think that a 327 in Littleton, CO., about 5400' in elevation is even going to approach 400 hp, or make enough torque to damage a well built 10-bolt rear.

I agree. @ 5800 feet, I have to get the carb jetted to help her to stop coughing. She's got a lot of giddeup but unless I hit her with NOS, it is not going to happen. She's been built to take NOS and about everything you can throw at her but I'm not that into it.

Are you talking about the women or the 10 bolt versus 12 bolt? :beers:You decide, it can be taken either way. Reader beware.

Just trying to bring some humor into life.

Nice to see we can all have fun on this. I was deer hunting when my 14 bolt started to "pop" slightly when I went around sharp corners. I went to the parts house to get some additives since it was an old posi. Sure enough, one of my hunting buddies just had to ask "whatcha doing"? I had to answer "lubing up my rearend"!!!!!!

Let's just say I stayed on guard for the rest of the night!!!!!!! :boxing:

Yeaowza

A well built 8.2 10 bolt can handle the 327 with an automatic. It will cost you around $1300 to build it right, which could go toward the 12 bolt, which starts at $1900. Your call. Is it worth the extra money for the 12 bolt?

Get the 12 bolt, It'll save you at least $600 worth of embarassment :o when that large, highly worshipped, supercool grey bearded rodder in a white XXXL Pomona "T" wearing sandals peeks underneath your car at your local cruise night.

Why would you be embarrassed to have a mild rear end behind a mild motor? WGAF what Joe Kool thinks or says? The extra $600 could be spent wisely elsewhere.

That would be kind of funny but I'm not to worried about other people. I'm building my dream on wheels. As long as I get the punch that I'm looking for, the traction that I'm looking for and the longevity, I'm cool with that. :beers:

My ride, my money. You don't like it, don't look at it.

Ok, let's put some numbers and parts down.

To rebuild my stock 10 bolt and convert it to posi without any worries, what would I need. Do I need to completely gut it? Plus, since I'm going this far, I might as well have it bead blasted.

How about a junkyard 12 bolt? Can they be found? What campatible chevy models will bolt right in without mods?

Keep in mind that I am also going to upgrade the rear suspension while I am at it. Those mono-leaf's suck and are forcing the rear to sag worse than any old lady. :D

Just another thought.....I picked up a '68 with a 396 and a super T-10, the only problem is it was sporting a 10 bolt with 2.73 to 3.08 gears at best. Fun with a 4 speed. Since I had been out of the scene for awhile, I thought I could pick up a 12 bolt posi for $400-$500 bucks. Yeah right. When looking for an alternative, I concidered a 9" because I don't have a numbers car. It's a plane Jane that I'm turning into an RS/SS clone. Here is what I found out:

You can fairly easily find '66-'77 Bronco big bearing 9" rearends in both 28 and 31 spines. What is sooooo damn cool is that the width is PERFECT for the first gens. The overall width is about one inch short which is also PERFECT (in my opinion). This was you can run a 15X8 wheel with a 3 1/2 backspace. All you have to do is knock off the ford perches and weld on new ones. You will also have to run early Nova style shock mounts to locate the shocks to the inside of both springs. Comp Eng. makes a bar that welds in between the subframe for more strength and the top shock mounts. This will look very sanitary and not look like you are trying to fit 10 lbs of crap in a 5 lbs sack. We all know how you get get much tire under a 1st gen wheel well without mini tubs. This gets you some extra room so your tire is not hanging out past the wheel well.

Oh yeah.......You also get the strength of a 9" without the "C" clips and tons of gear ratios. I picks mine up with a complete rebuilt posi and 3.70 gears for $550. What is you go bigger HP down the road??? The 9" will be there for you and the 10 bolt will be laying in the street.

Interesting. Did it come with the breaks and stuff as well? other than some small cutting and welding, does it look like it fits fine? Plenty of clearance?

What are the maximums of a built up 10 bolt? I really don't know if I'm going to (or can) build my motor up much more than it currently is.

Also easy to find are the 8.5" rears out of the 75-79 Novas and sister cars. They will bolt right in and are about the same strength as a 12-bolt.

It came COMPLETE. What I think is really cool is that I am doing the mini tubs next winter, and I won't have to mess with relocating the shock cuz it's already done. Here are a couple of bad pick to show how the tires sit. Remember it's a 15x8 that looks like a 15x7 until you see it from the rear. Building a 10 bolt, which you already have is probably easier, I just love the quick change of the 3rd member and all we have where I live is an 1/8 mile track.

I have a pic of the car when I bought it and now with the 9". Big diff in where the same tire sits. Yes, the car has a ways to go.......

BTW...It wasn't meant to be taken seriously.:D

8.2 cost--Eaton posi $450, 3.55 gears $180, installation kit $100, axles $205, axle bearings and studs $40, assembly $200 to $350. This may not include all the parts needed, and it might include parts that are not needed.

Is the standard 10 bolt actually an 8.2? Sorry for my confusion.

In the 1st gen Camaros the 10-bolt rears have an 8.2" ring gear. The 8.5" 10-bolt appeared in the 70's and is easily identified by the two square lugs protruding from the bottom. The 70's Novas were commonly equipped with an 8.5" rear that bolts right in a 1st gen Camaro.

Here's some info on the differences:

http://novaresource.org/axle.htm

The Camaro got the 8.5 in '71 and the Nova got it in '72.
