pre-65 Chevy rear end info-- anyone knowledgeable?
I have a 1964 Impala, and one of the first things I noticed when I got the car a couple years ago is that the rear end is different than the traditional 10- or 12-bolt style that you see now-a-days in RWD's. I just never gave any thought into it until now--I am hoping to drop a moderately-powered (headers,intake,cam,carb) 350 in to replace the 305 that blew up in it, and want to make sure that this older-style rear is not problematic. I know they ran 'em with the 425hp 409's and stuff, but I would still like to know what you guys think of this stock rear end/axle setup. Thanks!
-matt ramsey other car info: TH350 trans I have no further knowledge of the rear end (gearing, posi??)

 You should be OK........ With the automatic as a fuse.........and only a mild 350 up front...you will be OK. I tore up quite a few of them years ago....in a 55 Chevy 150 post car.....Hot SBC, 4 speed and a teenagers foot...... Have fun and good luck with your project. .

You shouldn't have any problems with it as long as don't beat it like Deuce said he did back in the day.
If you do have a need to replace parts in that rear later on you will find that a complete axle swap will be much cheaper though. You could almost replace that axle now and pay for most of the new one by selling the stock one you have to someone who needs a stocker for a car restoration project. But for now yours should have no problems with a 350/350 in front of it.

It should handle anything a sensible man subjects it to with a 350/350 combo. It is the last year of the 55-64 run and has all the upgrades of the early design flaws. If the car was power glide car, it most probably has a 3.08 gear. Other options would be 3.36, 3.56, 3.78 or 4.11. All had optional posi units.

Anyone getting info from this thread may be interested in knowing that I checked the rear gearing and it is 3.08 (original equipment was 283/powerglide).
