I'm probably the only guy on this board who has built one exactly to stock specifications with the stock heads and cam and dyno'd the thing on an actual engine dyno:

My take-away is that the cam is for tractors. No joke, it's really made to work well with a PTO. So any performance notion will come with a new cam. Then pocket porting the intakes of the little peanut heads. Then you're looking at better heads and intake.

With better heads and intake, it's a fine motor. With the stock cam/heads/intake it set up to idle and make torque.
