I recently picked up a type 1 engine that was apparently rebuilt to go in a plane. It has three extra threaded holes in the case around the pulley. Could they be for a bypass cooler, and can I plug them

Probaley a universal case that can also be used in a type 3 as they mount the engine hanging frame from those three holes as a type 3 doesn't have chassis horns as such

Here is a photo. The two bigger holes are on the left and right, the smaller one is down the bottom

Yep, 3 point mount case, used by VW for the later Kombi and Type 3 engine support bars

should be fine as they are only mounting holes for a brace.
