Air Chevy,
Welcome to the Bolt. You're likely to get a multitude of answers to any question you ask here. One thing I know you can count on is that you'll get an answer.
Back to your question. Unless you are planning on a period correct restoration, most of the group here will tell you to go the route of the 235.
I would probably join them, as you'd have a full pressure oiling system, rather than the old splash system in the 216.
Of course if your 235 is an early model, that argument don't hold water, and there would be no difference.
Myself, I have two trucks and two splash engines, 1-216 and an early model 235. For what I do with the trucks, they work just fine.
Bottom line... You need to determine what you really want to do with your truck, and how you intend to use it.
That answer could make a significant difference in the answer you seek.
