Welcome to the “Bolt”! A wealth of knowledge is at your fingertips and all you have to do is ask!
You may consider a later 235. I not sure but I think a ‘53-‘54 may just bolt in and is a full oil pressure engine. Maybe, another more knowledgable expert could chime in. A later 235 would also work with a few modifications. These are definitely more abundant and easier to find. They were made up to ‘62.
