I agree about that sweet
smooth little engine though, and the choice will have to depend on parts
availability and how fast I really think it has to fly when I get to that
point. 120-130 Kts should be readily feasible for the Corvair.

I would be concerned about that kind of speed with the Corvair cranks, until
the cranks cracking on the high speed airplanes (and even nitrated ones) are
more fully understood. I think caution is in order, in this case.
