I considered doing it. My son is putting a 1954 235 into his 1946 2 ton truck. I wanted to keep everything from the 46 motor kept together as I did not want to mix and match parts between the 54 and the 46.

Being the 54 came with the clutch housing I thought about having the adapter plate you designed made and used. But I did not think I would have enough time to have one made. Being my son uses his truck for his catering business I did not want to delay getting his truck back on the road.

Turns out the machine shop took so long to do the rebuild I could of had a truck load of adapters made.

So I am using the 46 clutch housing on the 54 engine.

I am going to put the 54 clutch housing on the 46 engine so I can mount the 46 engine on a 1945 1/2 ton rolling chassis. As soon as I can find a front motor mount. Jeffrey

Your adapter plate is why Stovebolt is a great place. I learn about great things that I may not use but is great to know because one never knows when and what he will come across in the future. Jeffrey
