I acquired these parts many years ago and were told they are off a 56 corvette 256 block. I have the block that I was told is a service replacement block that was cast in 57. I have other parts, engine mounts, timing cover, water pump and transmission hydrostick parts. I am interested if it has any value or is it scrap.
I DO NOT have a clue what that bell housing is for????????? It has a bolt pattern for a V8 engine------------but that is as far as it goes. could it maybe have been for installing a V8 in a boat??????
There is NO PROVISION whatsoever for a throwout bearing fork!!!!!!!! STRANGE!
I was told that in 56 the transmission engine was mounted in the front of the block and the bell housing had the rear mounts and that this was a bell housing as mounted in 1956 chevy v-8. I was told Corvette - but obviously that is not correct.
OK, obviously that bell housing is for that transmission. No question about that.
BUUUUUUUUUUT, I'm not familiar with that transmission. Although, COULD THAT TRANNY BE an early Hydromatic which was used in pickups beginning in 55?????
IF, just IF, that is what it is, then at one time, that was the hot setup!
The more I look at that bell housing, the more it APPEARS to have the truck style mounts. The 55-57 pass car bell housings had a flat surface for the mounts with TWO threaded holes. The truck housings had ONE threaded hole and a pointed guide pin.
Also, the flat surfaces for the mounts were at different angles for car and truck bell housings.
Yep, I bet that housing/tranny are from a 57 pickup with a V8 and Hydramatic transmission (those WERE NOT turbo hydramatics back then).
Hello guys,
Thank you for your knowledge and your comments. I have had these in a heated garage for more than 35 years, not knowing what they were for sure. I acquired them with the purchase of a complete 56 long block. There are actually two transmissions pictured. Both, I believe to be 4 speed hydromatics - I believe known as hydrosticks from similar photos I have seen online.
I am in balmy Minnesota where it is currently -22 degrees below zero with a -46 below zero windchill. I am glad I have a heated garage stoked to 70 degrees working on my GTO attempting to clear out some parts I have acquired over the years.
Yep, yep, yep, that's what it is. It's a 4sp Hydramatic transmission that was used in Chevy pickups (basically the same as the 4sp hydramatics in early Oldsmobiles).
After I searched my memory in greater depth, I remember that back in the 50s, some guys were running that transmission in their early (55-57) Sedan Deliveries. Even though the sedan deliveries were on a car chassis-------------------THEY WERE LISTED AND SOLD as trucks. Thus, an early sedan delivery could slip by the NHRA rules with one of these hydramatics because it was sold by GM as a truck-------------NOT a car. DAMN, that was a long time ago!

shipping cost for cast iron is high. Greyhound bus is your best bet. That’s garage art or a really trick nostalgic setup for a T-Bucket or similar custom build.
Sorry for all you people in the path of the frozen weather. Keep warm and safe.

Tom, is this the torque converter then?
If so, any recollection on the stall it might have had? Did it use a flex plate to attach to the crank?

Tom, that was around the time Robert Shaw was writing road tests for Popular Science and Tom McCahill was writing road tests fro Mechanix Illustrated. As you know, the 4 speed hydromatic was used by Olds, Cadillac, and Pontiac from the early 1940's through the late '50's. Very durable units for the day, and parts to rebuild them are still to be had. They were used in our Sherman tanks in WW2 which ran off of two Cadillac 346 flathead v8's....but you knew that, too!
I have, what looks like a clutch disc, that also is part of the setup. It must have had a pressure plate that was similar to a manual flywheel. I can dig it out and get a picture.

I DID NOT KNOW WWII tanks had hydramatic transmissions, but I DID KNOW that some tanks had Cadillac V8 engines. Also, while on the subject of WWII tanks, SOME tanks also had air cooled aircraft radial engines.
When I was in the Army in the VERY early 60s, The APCs (armored personal carriers) that we drove, had two GMC straight 6cyl GMC engines, one on each side of the vehicle driving a track. I always wondered what would happen to the mobility of an APC if one engine went out!
