Thanks Brett, we plan on doing prop and drive height testing this spring. The drives are 1.50's and i just got back from the dyno yesterday. I havent scanned the sheet yet but basically they build to about 640+ lbs of torque at about 3800rpm and stays relatively flat to about 5K. HP peaks at around 560+ at 5000rpm. We may bump the cam timing a bit to shuffle those numbers up by about 200rpm's, i think it will help.

Right now its winter an we cant go boating . . . . so we hafta talk about going boating :D:D

as always your input is greatly appreciated.
