Jim, The engine is a Lyc O-360 installed with DelAir STC. Lycon did some magic to the cyl before it was installed. The 3-blade MT prop shown is 79" diameter and weighs 54 pounds including the Kevlar spinner.

Guys, I have seen the comparative graphical results of FAA required prop/engine vibration analysis. 'Have also seen the resulting vibration damage to the hub/blade retention system. I would strongly advise to heed the RPM restricted range if it is part of your propeller/engine limitations section.
