I am in need of some advise.
I have a 1956 or 1957, 235 engine.
I want to install in my wife's 1948 Chevy pickup.
The problem she just had double hip surgery.
I want to put a 350 automatic transmission in the truck for her.
how can i do it? the bell housing has the mounts that holds the back of the engine.
The automatic dose not have the mounts.
Thanks for any advise.
Dave

You will want to make mounts for the side of the bell housing to help support the weight of the engine and transmission. Since the front of the engine sits on a mount right at the front of the engine, you will need something at the bell housing to help with the weight or you will break the transmission case. | | | | | Joined: Feb 2019 Posts: 8 New Guy | | New Guy Joined: Feb 2019 Posts: 8 | The 350 transmission is i think is cast aluminum.
I don't know how to make mounts for it.
Has anyone out there that has made mounts?
If so do you have any photos?
Are their any other transimission that would work? | | | | | Joined: Feb 2004 Posts: 29,887 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,887 | A Powerglide transmission from a 1955-61 Chevy car with a 235 engine would be a lot simpler to swap, but you'd still need to do some custom fabricating of the motor mounts, driveshaft, and shift linkage. The PG is a cast iron case 2-speed, but there was a factory 235/Powerglide option, at least for cars. The TH 350 was never offered as a factory setup behind a 235 engine. Making that one work requires a custom-made flex plate, an adapter plate to mate it to the 235 engine, and a different starter. Then the crossmember at the bellhousing would need to be modified for rear motor mounts that adapt to the 350 trans. There are bellhousing mounts to adapt a TH-350 to a 55-57 Chevy passenger car, but none that I know of to do the same thing with a truck. It's going to take some custom fabrication, either by yourself of someone with the skills and equipment to do so.

Jerry , would an adapter used to bolt a power glide to a 235 accept a turbo 350??

You can make the modern engine look older with the right paint color. Trying to adapt to the 235 is going to be a very big job, meaning lots of money ! | | | | | Joined: Feb 2004 Posts: 29,887 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,887 | No, the adapter ring for a PG is basically circular, and only about 2 inches thick. The bellhousing of a PG trans is nothing like the shape of a 350. The Chevy-pattern 350 bellhousing would be a direct fit to the 3rd-generation inlines like the 194, 230, 250, and 292, all the V8's, and some of the V6's. It will also bolt onto the "Iron Duke" 4 cylinders like the Mercruiser or the 4-cylinder Chevy II engines.

Ok thanks Jerry. I have a couple of those rings hanging around , I guess they would be rather worth less then?
