I know Hartzell did do Vibe testing on the O-360/IO-360 with EI, which is what resulted in the 7497 replacing the 7496.

There are hundreds of planes flying behind the 360/7497-2 setup, that is the known/tested quantity. The reality is, if you go with an experimental, low volume engine, you can't expect a value-minded manufacturer to test every single engine/ignition/prop combination.

I'm with the "It should be fine" crowd, I'm sure there are plenty of them flying, and I haven't heard of a single 7497 coming apart yet. MTV-9's on the other hand?
