Micheal, I think you see why now I don't do dyno's...except to tune. I can care less what the numbers end up, only that we are within parameters not to lean out. Your numbers are believable, but if it were tuned, I would expect it to have been tuned to a 65mm pulley or if luck would have it, a 185 crank pulley but doubtful. Most ran the 65... You don't need to touch the internals on the engine...nothing to gain there... Leave that hand built motor alone...lol
