    you wernt beating on it where you? I wouldn't take a freshly rebuilt motor over 3500rpm for at least a 1000 miles until you know the pistons are properly seated

    your supposed to go throughout the whole rpm range under full throttle then off the throttle,tha vacuum in the engine will seat the rings properly,

    I usaully go with a power steering bolt hole, and take out the starter and use the top starter bolt hole, seems to bring it out steady and dosent dig into anything.
