I'm still somewhat lost on what rear end to run under my '53. It is getting a 383 stroker making just shy of 500hp at the crank and I will also most likely run a 700r4 behind it.

I would also like to run a 8" wide rear wheel if possible. So are there any readily avaliable (ie: pick n' pull) axles that would hold up to this engine and be narrow enough to run this wider wheel? I will also be upgrading to 2.5" leaves.

Thanks again!

The best drop in fit for that power train is not going to be easy to find. A 12 bolt posi from a first gen camaro or firebird (or nova) would be the best fit and most durable. It has a 60 in. dimension which is the same as your 53.

A second gen camaro/firebird third member will fit and is plentiful but good it isn't going to be as strong. Then again, it may not fail before the 700r4. It's 61 1/2 in. but it would carry the 8 in wheel easily. You would probably need a 4 or 4 1/2 in back spacing depending on the tire you are running.

I think the 10 bolt would be okay, because the car is too light, you should be spinning the tires before you can hurt the rearend.

There are some Ford 9" rears with a 60" housing too, if you want to go that route.

But the second-gen Camaro is probably going to be the easiest to find in the you-pick, if the S10 is too weak for that kind of power.

Those who can, do. Those who can't, criticize it on the internet.

Thank you both for the advice. I plan on using the Chasiss Engineering leaf spring kit and it shows they have a kit for the 67-69 camaro rear which is a 10 bolt, correct? And I assume with this kit and the correct rear end it should be a straight forward swap.

Anything else I need to check out at the junkyard when looking for a rearend? Were these posi units and what ratios did they come in? Thanks again and I appolagize for the ignorant questions.

Here's a chevy axle chart that I had in my bookmarks. It lists a bunch of information on the Chevy rear ends.

I honestly think it's highly unlikely to find a first-gen Camaro in a junkyard. A Nova that era, sure, there's a couple 74s in a yard here, but the first gen cars I have only seen in older yards where they've been rotting for 20+ years and that's getting harder and harder to come by.

Does anyone know what Ford 9" rears would fit this application if I decided to go that route for more strength? And if I run a 8" wide wheel what would be the ideal width? 60" like the stocker? Or wider or more narrow?

Thanks!

An 8 inch F**d rear out of an early mustang is the right width. Don't know about the 9 inch.

A 9" would be the strongest, but pricey. I went with an 8" from a mid to late 70's Ford (this one just happened to come from a '79 Monarch) Not quite as beefy as a 9", but stronger than a 10/12 bolt GM rearend. One downside is the difference in bolt pattern. You can get different axles or have them redrilled (sometimes) but then your into it for more cash.

The Monarch/Granada/Versaille s are the same body... seems like the Lincoln one usually has a 9" with disc brakes. They're not super common either but they're not quite the unobtanium an early Camaro is going to be.

OPEN DRIVELINE CONVERSION

To convert your torque tube suspension to a open drive line. You will need the proper width rear-end. I am running a 1976 camaro 10 bolt.

These are some swaps that will work.

* 55-57 Chevy Cars. (57 is best choice)
* 68-72 Nova
* 70-81 camaro

For 49-54 cars,you will need a rear-end that is 60" wide. You can use the stock leaf springs but you will get a much better ride with a wide leaf spring kit. (2.5" wide) If you run a rear-end that is 58.5 inches wide you will be able to run a 8" wide rim (3 3/4" backspacing)in the rear.

Thanks again for everyones help. It looks like a 58.5" rear is what I am after then. And that measurement is simply taken from wheel mounting surface - to wheel mounting surface, correct?



EDIT: I found Ford 9" this chart while searching, please don't hang me for posting this on a chevy site!

Anyways, which of these other axles would be close enough to work in my '53 with a 8 wide wheel? How about the Bronco rear at 58"? Im just thinking a versailles rear might be scarce.

If you were willing to get custom (or corrected) backspaced wheels, would it really matter if you were running a 58.5 inch rear end?

I have a disc brake 3.45 posi 87 trans am GTA that i believe is 62" wide under the 50 chevy i'm working on right now, and it fit great with normal wheels. I plan on getting 8" wheels and setting them up with correct backspacing, and haven't seen any clearance issues while working under there yet.

I left the axle stock and made the frame coil spring 3 link with watts linkage, so i could get a Ford 9" or Chevy 12 bolt that's made to drop right into that generation firebird camaro, and it'd be bolt in.

However, i don't think all that affects the wheel spacing issue at all.

here's a bunch more information on the different rearends and front clips, etc..
The first gen camaro is slightly narrower than the second gen (70 - 82). First gen is 60 on the rear and approx. 60 1/2 on the front, which is almost exactly the same as your 50. This measurement is mounting surface to mounting surface (outside hub). The second gen is 61 1/2 on the front and 60 1/2 on the rear, mounting surface to mounting surface. Scroll down near the bottom of the info below and you'll find some clip measurements.

Sixshooter, I have a Ford 9" rear under my '52 hardtop.I had this laying around.(I used what I got ) I also have the Chassis Engineering rear spring kit. The spring kit is super EZ to install, hardest things are removing the old spring perches(drilling the rivets) and drilling holes for the upper shock mounting.
The rear I have is from a '64-'71 full size.I measured it at 61". I installed a traction lok from a '69 mustang and set up with 3:50 gears.I'm using the stock axles.I also converted to disc brakes in the rear. 1990's Lincoln came with discs from the factory and will bolt on with slight mods. Theres a ton of aftermarket avail also. Jeff
Heres a link for the rear specs widthshttp://www.carnut.com/specs/rear.html
also a link for wheelspacing for the tri-fives. there the same measurments as our cars (i'm told)

I'm going to use a 94-2002 or so Ford Explorer rear axle in my 1953 Chevy. The axle has 31 splines, disc brakes, and a factory posi. Width is close to 60". And you can get them cheap at junk yard. The pinion is slightly offset, but I haven't found anyone who has had a problem with the axle.

I'm putting a cammed and carbed 2009 5.3 in my 1953 Chevy. I should be around 425 hp at the crank. I don't expect a problem with the axle.

To my knowledge, Ford designed their rear with the offset pinion so the needle roller bearings in the universal joints for the driveshaft would rotate and not wear "flats" in them if just the universal rotated. Anyone else heard of that? Jeff

I just picked up a 8.8 out of a '92 Explorer today. It measures 59.5" and came with 3.73 limited slip. I also noticed the pinion is offset, it looks like about 2 1/2" to 3". This shouldn't be a problem should it? I also ordered the CE rear kit today so I'm pretty excited about getting this rear end in there and moving forward on this car.

Thanks for everyones help and input.

I thought it was because they are 4wd.The shaft comes out of the transfer case,so they offset the rear end to get a straight shot.???????

I believe that is correct lead sled. I'm just wanting to make sure that there won't be any issue running it with this offset in my car. I have heard it is no issue, but I would just like to verify.

What about the strength of the Explorer,Blazer rear ends. The 9" will handle a 350, but will the Explorer and Blazer do the trick?

I hear of a few guys running 8.8 rears that are running mid 10's and 11's with full slicks. Also, the explorer rears are 31 spline, I believe most others are 28. Pretty stout from what I'm told.

You are correct. Explorer axle is 31 spline, but some Rangers also have the 31 spline. Most Mustangs are centered (chunk) with 28 spline. I've heard the Mustang guys put hell on their 28 spline axle 8.8's. So if I come across one of them, I'll definitly buy it.

31 splines is not the sole measurement of a "stout", reliable 3rd member.

Well, after all the above discussions, let me jump in here and provide some comments on the 55-64 style rears (as though I've never said a word about them in the past ).
I know, I know, I know the 55-57 axle housings are becoming kind of scarce, but there are still plenty of them out there and it is one of the best options for converting a 49-54 Chevy to an open driveline.
Now first, let me preface this with 2 comments:
First, the 55-64 rears are perfectly fine, and plenty strong for any healthy SB in a car that is a street/driver/performance car-----------------I'M NOT TALKING HARD CORE RACING WITH STICKY SLICKS!
Second ------------ EVERYBODY seems to forget that this style rearend was used behind the 63-64 425hp/409 engines. And they only broke under excessive abuse conditions.

IF, IF, IF a 55-57 axle housing is used, the BEST CHOICE center section to use is the 60-64 posi. Or, if you can't locate a 60-64 posi center section, then at the very least install one of the new Eaton posi units in a non-posi rear.

It's true, all 55-64 axles are 17spline. Again, these axles were used in the 409 cars and did just fine as street drivers.
I have a 57 axle housing under the 51 Chevy that's been there since I converted it in 1967. The rearend center section that's in it is a 3.08 posi that came out of a 64. It's been there since late 70s behind a healthy 327, then a healthy 350 and now the 51 has a very healthy 383. I run 235/70R15 tires on 15x8 Corvette Ralley wheels and everything works just fine. I no longer do any serious clutch banging, but I often turn some serious rpm's. Last Sat when I was going to work on the plane, I was running with a late model Volvo on the Interstate at 110mph for about 8mi (surprised his a$$).
The 55-64 ring gears are 8.2, so certainly anything that size and larger would be a good choice to stick under a 49-54 Chevy.

Call me crazy but i want to change my rear end but still keep the 235, I just want a different rear end just in case one day i decide to convert over to a diffrent eng and trans setup plus it will be nice to drive this thin on the freeways and not worry about putting to much stress on the engine. so is it possible to change the rear end and still keep the 3 speed and 235?

Johnny,
READ THIS CAREFULLY!
If you swap to an open rearend, then you will have to change EVERYTHING from the behind the engine. There IS NOT any kind of way that you can keep you existing bell housing and 3sp tranny. Your existing tranny ONLY connects to a closed driveline (torque tube).
You will have to change the tranny to one that connects to an open driveshaft. But, to be able to change to an open style tranny, you will also have to change the bell housing to a 55-62 style bell housing (or an early 50s truck housing). The bolt pattern for the tranny on the rear of the 54-earlier housing and the 55-later housing is totally different.
You can bolt ANY 55-later tranny to a 55-62 housing, such as a 55-later 3sp or 4sp. If you want to stay with a 3sp tranny, the 58-65 3sp is an excellent choice because it has a SHORT tail housing, AND, it has a tranny mount on the bottom of the tail housing. I pointed out the shorter 58-65 3sp specifically because it is easier to work with than the longer 55-57 tranny and because the 58-65 3sp has the tranny mount which makes it MUCH EASIER to adapt a tranny mount to the 49-54 cross member.

Now, my last comment.
THE 49-54 CHEVYS WERE NOT DESIGNED FOR THE INSTALLATION OF AN OPEN DRIVELINE!!! Thus, depending on what you go with, there WILL BE some fabrication required. THERE IS NO SUCH THING AS A DROP-IN, BOLT-IN CONVERSION TO AN OPEN DRIVELINE!!!
I did the conversion to open drive line on my 51 about 45yrs ago, and it was somewhat of a hassle then. Nothing's changed. Today, there are more rearend options to choose from than there was 45yrs ago, but modifications and fabrication is STILL required. I just don't want you going into the project thinking it will be a piece of cake!
