Remove the spark plug and rotate the engine thorgh several revolutions by hand. If you don't feel any rough spots in the bearings as the crank makes full rotations, run it.

I have two 3.2's also. One of them was mounted in a G/P Pitts, making prop strikes almost a sure bet with the way the landing gear was set up. After several broken wooden props, I'm still continuously flying the engine almost a year after the fact with no ill effects.
