Hey CY, Ive got the same motor. I just rebuilt mine myself,and still breaking it in. Ive run it to 3500 rpms but only for a few minutes. Im not sure how accurate my factory tach is. It seems to run really smooth with no strain about 2800-3000. Im not sure about the speed, cant get my Hummingbird to tell me how fast Im going. Are you still running points or have you converted to electronic ignition. I installed a pertronics ignition,runs good but dont want to fire up when its hot.
