I have an SS Malibu, 1965. I bought it 8 years ago and it seemed to have most of the original stuff... I got the wheel off the ground and spun it, counting the driveshaft spins and got about 3 1/3. Since it's a 10 bolt, that makes it non-posi, right? and it would be a 3.36 most likely? I found no numbers on the housing or the axle near the housing. It is dirty, though! I might as well change the fluid anyway, so could I drain it and take the cover off to make a positive ID? What am I looking for? Count the teeth? And what fluid to use to replace?

Lots of rookie questions. Thanks-

The ring gear will probably be marked. It will have the number of teeth on the ring gear and the pinion gear marked on it. You can also count the teeth and divide the number of teeth on the ring gear by the number on the pinion gear.

Hi Rich,
Jack up the car with both rear wheels off of the ground. Spin the passenger side tire. If the driver side tire goes in the same direction, you have a Posi. If the driver side tire goes the opposite direction, you have a non posi. If the driver side tire does nothing, you might have a Posi that has a worn clutch pack in need of rebuilding. When you have the 10 Bolt Cover off, see if there are numbers cast on the center section. The last 3 numbers for a 3 Series Posi Carrier are 116. The last 3 numbers for a 2 Series Posi Carrier are 118.
Hope this helps.

Many thanks, guys...

37/12= 3.08

So I have an open 3.08 gear! What a powerhouse. ll

Was that a standard gear offering in 1965?

 

[mino65]

yup!!

 

[richietables]

yup!!

Well then, the mighty powerhouse 'super sport' came with a 283, 2 barrel, 'glide and 3.08's! lll

No, that's cool-- I love driving the thing.

Well, it was actually a decent gear for mileage......

I changed my '65 10 bolt to a 3.55 with a T350 and mid-modified 350 and ran 14.3 in the quarter.

(With the 3.08, PG & 283, I once managed to get it up to about 95 MPH before it pooped out... actually it pooped out long before 95... but I had a good tail wind.)

 

[richietables]

That's right, Mike. I do get decent mileage with that gear. It just is different than I thought it was all this this time... I'm glad I checked! You never know what you have until you actually look. Well, I changed the gear oil, at least... Who knows how old that stuff was.

 

[SPARK69]

Hey the gas mileage is good!! Hahahahaha

 

[mino65]

What ya gonna do with the 327???

 

[richietables]

Actually I'll probably drop another cam in it and swap it back in a couple of years! Maybe with the 305 heads..... (that motor kicks a$$...)

 

[Stalkingbear]

My Elky '68 is a 3.08 rear..... with the 350 it is peppy as long as you go through the gears. Try flooring it in 3rd at 50 and it is a dog.

 

[richietables]

Mike, I liked it when I thought it was a 3.36, so I guess I got no right to beef!

 

[JAYARTER]

YOU COULD ALWAYS PUT A 327 CRANK IN THAT 283...
THOSE MOTORS RAN GOOD THAT WAY MANY YEARS AGO

RICH THERE IS A BOOK CALLED "CHEVY BY THE NUMBERS"
covers 65 to69 its the best book i've found and just about
everything from vins to motors

see ya jay :yes:

 

[Stalkingbear]

... or put the 283 crank in the 327 and have very little torque and gobs of horsepower. It would be a 301. High reving whining machine - fun to drive BUT..... I personally think the Chevelle is too heavy for that engine. Works great in a '64 Nova or something light. I built one for my Nova when I lived in Tucson and worked at Eastside Engine down there.

If ya did that you would have to change that 3.01 gear to something with a bit more dig in it.

Thats the way my first 65 SS came. I thought I had 3.55`s but once I pulled the cover and counted the gears it was pretty clear what I had. Ran 13.0`s with a peg leg 3.08 and slickes with the 327 I built for it. I miss that car and should have kept it stock and found another body to drag race with.

 

[richietables]

No! You guys, don't confuse me! Stroking this motor, DE-stroking that motor! LOL... I have the 283 totally done and am just waiting for a break at work to make the swap in a couple of weeks... Once I get the 'butt dyno' feel (probably close to the feel of a 1985 Honda Accord with an automatic...) with the 283, I'll know more about what I want behind the engine. Jake had a 200-4R that I was about to pull the trigger on, but with the gear I have, I'm thinking now more like the 700r4... Have to get the motor in 1st...

Now--- When I get sick of the 283, l , I'll want a ton of ideas about what to do with the 327 again! It's .060 over with double humps and NOT original to the car, so that'll be a fun project!

time...they built my flat head motor i have in the garage

[Stalkingbear]

I left there in Sept of 1990..... I enjoyed working with Herb & Dwayne. When we were in Tucson this summer I stopped to see them to say hi.

 

[JAYARTER]

I think they did my motor in the early 80's

it probably has 10 hours max since... Kids, wife, exwife
and buddy burned down the garage don't ask
