i should expect a motor to last a good 75k miles of abuse before pulling it for a refresh. but define refresh? are you talking just new bearings and rings? or replacing pistons rods bearings? are we rebuilding the heads? what about the crank? i mean what is a refresh? Its a tough topic for sure on when to decide to pull it and have it gone through.
