with good tires, good engine you will be at 3200 rpms going 55 mph. I run a little below that on the flats. if you tires are completly bald you will lose some speed due to loss in tire height. New tires vary in height between 35 and 36.3 inches. if yours are worn down to 33.5 it will effect op speed. a flathead in good condition can run 3200 rpms for extended periods of time. but if you have an old tired engine 3200 rpms will wear it out kinda fast
