I really just need to get a tach and my GPS some new batteries to really see what my numbers are. Not a mechanic by any stretch so my numbers in the earlier post were just and unedgumacated guess. I honostly probably have no idea how loud 3K RPM's sounds at freeway speed in a full vert. I know it could be searched on here but what would you say is an acceptable higher rpm to run for several hours non stop on a 400sbc? 2700? 3000?
