Based on your rebuild specs, the only limiting factor I see after the first hundred miles and an oil change is the limitation of the dipper-tray oiling. Eventually you reach a point where constant high-speed operation will cause sufficient tray windage to starve the rod bearings. Exactly at what RPM is debatable, but I know guys who run thousands of miles at 60-65 with 3:78 and no O.D.

I'm not one to hold back much on break-ins or agressive running. With modern rings (used in your bowtie pistons) and full insert bearings, after the first 100 mi. I'd let her rip.

The only question I see is are your tires/wheels/balance/bearings, front end, shocks & brakes up to the task? Got seatbelts?
