Is there any other way to ID a 235 other than the block number?
Next to the distributor is 052T397F54M. This has to be a rebuild number. It goes in a 1954 model 3100 with a hydra-matic, so I assume that it is a 54 block because of 54 in the engine number.
I am trying to check into carbs and all the info I can get will help. The exhaust manifold has a heat riser but the carb is a Rochester B with the manual choke. How many companies rebuild these engines, I may try and contact one for a record of the rebuild.

Thank You
