But would he not go past 10:1 static CR and then get in the regime where he could not readily run pump fuel? The AL head chambers are in the 62-65 cc range. Seems like the cam to run pump fuel with the significantly higher CR of domed pistons would be getting pretty big, so might not suit the 'cruiser' use, and get into fuel mileage issues too. (Of course, that's 'big' relative to a typical 268 cam.)
