Have him preserve the engine for storage, and put into the logs what he did, including that the engine hasn't been run as of that date. Circumstances change and people are sometimes unavailable, and that way you'll both be covered.

Personally, I would not run the engine without the wings on. Too many reasons not to with no obvious benefit.

I feel that the most desirable sequence is to get the plane as far along as you can and then prep it for flight. Once it's ready to fly, any remediation or further development can be handled like it would be for any other flyable aircraft.

I ran my wood prop 150 hp rv-4 no wings and no elevators or rudder no damage my friend ran his rv-4 180 hp cs no wings with elevators and put a cress in the one elevator.
