Orma, When I built the engine for the Little Beast, I messed around with a lot of cams and seem to remember that our engines turn slowly, compared to racing engines. For that reason, I remember something about long duration. I hope that Bob Hoover will chime in here, because he is the expert. If he doesn't I suggest that you check with him before doing the cam thing. Also, Steve Bennett may have already figured this one out and you might want to check with him.
