    So, what kind of rings are on the pistons?
    If you have moly rings............just break it in for the 20minutes to get the cam/lifters seat properly......................and leave it at that until you get insurance or whatever..............the running up and down the rpm range should really be "under load", but you can always do that later. Whatever you do after you break-in the cam..............don't let it idle.
    You are going to break-in the motor in the car?????

    I agree. My dad was a Ford mechanic and if I did'nt know any better I would have sworn that he wrote this.

    Any break in i do i would use a break in oil definatly (like royal purple, joe gibs, etc) once u start it set timing quickly and bring up ur rpms to around 2,000 for ten to twenty mins. After that shut it down drain the oil if u can afford it and replace ur oil filter. after that u should be good to run your new motor. I personaly baby my new motors for awhile haha

    No problem, It was a compliment. My dad did not race him self but built many full race cars for a lot of people.
    I do miss that.

    I heard a while back that you should break in the engine relatively quicky after it is brought up to operating temp. By allowing the rings to wear on the cross-hatch honing in the cylinders for an excessively long period, it creates a type of filing action against the honing and prevents it from properly seating the rings.

    "Break it in the same way you're planning to drive it."

    Again, that's just what I've heard.

    It depends, if you have a flat tappet cam, or a roller valve trane. It also depends on what type of rings that you have. You can NOT break all engines in the same way!
