That 1953 engine is a rare "oddball" engine. Give it great care (as if I have to say that).
I hope your engine does not need that "snake oil" fixture, Carl (but if it does, it would be a good conversation/BS assembly).
The '53 with Powerglide 235 is pretty much the same as the '54 truck engine.
The differences I have found are:
They have Captains bars above the starter.
The back of the crank shaft was not machined to receive a standard pilot bearing. (A pain.)
They came with the 216 style valve cover. (Really cool.)
They came with aluminum pistons and hydraulic lifters.
