I don't like a sq or over sq motors.the thrust angle and the big slug your trying to sling..
Remember back when the Nascar guys were destroking there motors making more power.
Also why do you think Sterling is running that cube, they have people spending $$$.I bet the experimented on a few costumers I would think they figured it by now whats the best combo, again there looking at max hp in a race application and usually have a higher RPM peek hp .I would think The bigger the ci the lower the RPM.
