No matter the power level, to keep things safe, you generally wouldn't want to push a flathead much over 4500. 5000 is about the max on a well built engine, a little higher back in the day when the engines were considered expendable and easily replaced. 3 main bearings and a less than ideal valvetrain really limit them.
