    Still a little over a month away, but Im a prepared son of a gun. Like to think things over. Anyway, Im wondering what the correct engine break in schedule would be on a roller top end 496 new cam, crank, rods, pistons, etc. I mean from second of startup till 5000 miles. What all should I be doing during these vital miles? Oil choices? I want to end up on Synthetic, but I heard that you shouldnt break an engine in on it, any truth to that? Just give me an idea, mileage wise also, when I can finally take this beast offroad. One final thing, I hear that in the first 20-30mins the engine will get HOT, as in, header glowing red etc. Anything I should do so I dont roast this pig? /forums/images/graemlins/truck.gif/forums/images/graemlins/usaflag.gif

    After the intial firing and checking for leak's, setting valve's, timing, etc. Change the oil and the filter.
    After say 500 mile's, change it again, and then just every 3000 mile's. /forums/images/graemlins/eek.gif

    Do not break the engine in on synthetic. The rings may not seat and you will have a smoker for life.
    Shelve the sythetic until the engine has 15000-20000 miles on it.
    Just vary the engine speed, no cruise control, and be sure to get on it about 3/4 throttle every once in a while to build heat and seat the rings.

    I guess with a roller you dont have to run with no load 2500rpms for 30 minutes like a conventional cam

    I have a roller set up in my 454 and it's just like MJ said. There's no need for the 15~20 minute break in like a flat tappet cam, just run it easy for a while to seat the rings and then let her rip.

    **On my motor** with the initial start up my buddy (<font color="orange">TARussell</font>) and I would check for leaks, oil pressure, etc. and then abuse the crap out of it, never had any problems.
