I will try and answer your questions as I understood them. First I will say choose the 351C over the 390. You stated that which one give you the most punch for the buck, that is going to be tough with either one of these motors both have pricey replacement parts. How complete is the 351C?
I am also with Rev that a 351W is a nice motor to tweak and does not cost you a arm and a leg.
