At this point I don't recall if it was careful parts selection or pure dumb luck but I think it was a close fit although I do remember it not having a lot of spare space. There are a variety of thermostat housing castings, each a bit different from the others WRT wall thickness, clearance angle at lower front and overall bulk. There are also slight manufacturing differences in the throttle linkage across the front of the engine that can help/hurt. And... there are several different casting numbers of each of the 1 and 2 hole pumps that vary slightly in shape (plus aftermarket pumps) to add or reduce clearance. I remain very nervous about the idea of modifying the 2 hole 216 block to accept a 1 hole pump. it just looks like more holes, closer together than I am comfortable with - but it might be alright in spite of my nervousness.
