    When I ran a rebuilt engine in then I followed the advice of a tuning book that advocated going out and giving the car full throttle at low rpm up to about 50% max rpm a number of times to help push the piston rings out and get them started on the bedding in process. Then it said varied rpm and loads with the max rpm gradually increasing as you added the miles. It doesn't matter what speed you go at, just limit the peak rpm at first and show some mechanical sympathy.

    Oddly enough, good oils can hamper the running in process, so I tended to use cheap stuff and change it after 250, 500 and 1000 miles, but that's enthusiasts for you. See what the manual says.
    Happy chappy
