I actually did consult with Ken a few weeks ago and he was very helpful in guidance. Unfortunately being in Jersey I could not directly benefit from him direct attention. He did provide some history and data of re-propping a 377 but most experience with Verados. Seems the main finding was mounting level and he found many were mounted a bit low impacting performance.
I am making progress and was fortunate to have a dealer that has a selection of props to work with. I am currently working with the Rebel 15 1/2 x 17 and seems to be the right combination. I am getting much better mid range performance and economy without loosing top end speed.
Thanks for your reply and agree that Propgods is a great resource. I would definitely use Ken if I lived in Florida.
