I know aluminum is what people run to go faster, but...., in the interest of reliability, wouldn’t a steel rod do the job. Both of my 580 inch motors have steel Oliver’s, and one is shifted at 7400 and one at 7600. I know I sleep better because of it, probly giving up some power. Curious if anyone has a rough idea how much. Jim
