Ron, thanks for taking time to post this! It is exactly the kind of information I need. You and Gary have helped a lot. Man 1.25 lbs. Per cylinder. I'd sure like to see/hear it make a pass! how far do you take it above that 3500 rpms? I'm going back through old posts looking for info and sorting piles and drawers of parts to see what I need. Thanks again, Tom
