The Stovebolt Site Forums The Shop Area Engine Shop WILL A '63 283 BOLT UP TO A '62 PG

I have a 1962 with a 235 & PG Trany. I found a 283 out of a '63 Impala that I want to put in it. Some people say it will bolt right up, others say the bellhousing is different on the 235. Does anyone know for sure if it bolts up or not? :-)

Thanks,
Clay

Hy CLAYCROGHAN, I believe the 62 powerglide is still a cast iron housing transmission, if it is, it will have a small adapter at the engine end, you could swap adapters for one from a V8 powerglide of the same vintage, you will have to find a V8 powerglide flywheel as the 235 flywheel will not fit the V8. If your 62 powerglide has an aluminum housing it will not bolt up to the V8, hope that helps.

Thanks, might just throw in a TH350 and call it good, just trying to keep it halfway Original.

The factory installed trans in '62 was a cast iron Powerglide. I had one many years ago. I don't believe the aluminum case tranny was ever offered behind the 235, but I could be wrong about that.

alum p/g was not in production until 63.
you need a p/glide from a 283 in 62 to fit a later 283

Then explain to me why my brothers 62 Impala had an V8 w/a Alum PG in it & he bought it from the original owner and so did my 62 Nova w/a 6 cylinder. Both were air cooled PG, no trans lines...Joe

The Aluminum Powerglide was used from 1962 until it was replaced with the Turbo-Hydramatic series of transmission in the early 1970s


The early 62's may have had them but I know for a fact that BOTH the Impala & Nova I talked about had aluminum PG in them...Joe

I would go 700R4 or 200R4 before putting a TH350 in.

Both the '62 Belair and the '62 Impala I had years ago where cast iron Powerglides. I'm pretty sure the Belair was original but I know the Impala was not because I bought it without engine and trans and stole the stuff from the Belair...

I later put that some engine and transmission in a '41 Chevy 1/2-ton.

But back to the topic, I don't believe there was ever an alloy case 'glide available behind a 235, so the proposed swap here probably involves a cast iron case and the requirement to find that adapter ring that goes between the motor and tranny.

Now as I've said I don't think the later transmission was used behind a 235 it occurs to me to wonder what automatic transmission was used in those Canadian Pontiacs that used 261s. Anyone know?

cast iron powerglide
there was also a turboglide used i believe from 57-61
. In 1962, GM started building Powerglides in aluminum (primarily for use in the new model Chevy II, which required a light weight transmission for the compact body) and discontinued the cast iron Powerglides in 1963.

The cast iron powerglides on V-8 and I-6 engines are different. Althought the gearboxes are the same, the converter housings are different because of the different starter locations. To connect a V-8 to an I-6 powerglide would require the V-8 adapter (flywheel cover) and swapping the conveter housing.

You only have to swap the adapter ring to change a cast iron powerglide from 6 to 8 cyl. Also These were not "Air Cooled" they have cooler lines. I have on in a 60 BelAir and it is the original tranny that came in the car new. Better have a strong jack to lift it. I bet it weighs almost as much as the engine. These are a neat tranny. it has 2 pumps one in the front and one in the rear. The rear one would let you drift off a hill get up to about 5 MPH and drop it in gear to drift start it. I had to do this alot before I swapped out the gen for an alt.

The cast iron powerglide converter housings are different and must be changed to move the transmission between a V8 and I6. Here are pics of a '57 235 powerglide and a '57 283 powerglide.

I'm pretty sure the early 60's I-6 tranny was identical to the V-8. Might be the year diff. Cant be 100% on that, been about 15 years since I was up to my elbows in the old Chevy's. In all I had about a dozen 60 61 62 and 63 full sizes in the 80's people were giving them away to get them out of their yard.

This was a reply to my search for a adapter plate in the PARTS WANTED FORUM:
(Quote)
The factory Powerglides in the '60-'66 Chevy trucks are the same, whether attached to a factory V8 (283 or 327) or a factory straight six (230, 235, 250 or 292). I don't think you need an adapter plate to mate a Powerglide to a sbc.

Does any body know if this is TRUE, Has anybody done this installation? I would like to find out before I start buying Adapter Plates, new Tranys, etc.

Thanks,

The conclusion and some of the facts are wrong.

The 207/216/235/261 (Chevys) and 228/248/270/302 (GMCs) have a much different bell housing bolt pattern than the later 230/250/292 and the 283/327 and other GM V-8s.

If you are trying to put any of those motors in front of an early Powerglide that was originally attached to a 235 you DO need the right adapter.

I wish people who don't know what they are talking about would step away from the keyboard.

That's kinda what I thought. I guess i'll REALLY find out when I get the engine out.
Thanks for the reply.
