Do one heat cycle to check for leaks, set the rockers, etc. Let it cool back off, then drive it, so not abuse it but load the engine to seat the rings. 1/2 to 3/4 throttle up through all the gears, then back down through the gears (important to go both ways).
For the first 50 miles or so do not hold the rpms steady, such as interstate driving.
Change the oil after 50. Then let it rip, providing the tune is right, take ir to the track and put it through the paces.
Change oil again after 500.
Im going to run a 15-40 diesel oil (DELO) for the first 50/500 then switch to german castrol or pennzoil platinum ultra

I've always believed an engine will "act" like the way it was broken in. Go out for some "Spirited" driving after it's warmed up the first time, lol. I've actually used a steep hill a few times and it works pretty good.

I've done pretty much same process as listed above. Run it through the gears varying RPMs for 50 miles (no WOT) change oil, inspect the drain plug and filter just to make sure there's no abnormal wear, then take it out, and tear it up. I normally change oil at 50, 500, 1500, 3000 (using Rotella T5 10W30), but that's just because I'm very careful and if anything is wrong or not set right, I like to know about it. My machinest always told me if he built 2 identical motors; one for a high school kid, and one for an old man, he would never see the high school kid again, but the old man would be back bitching 2 weeks later about oil consumption. So take this as an oppurtunity to "be young again"....or at least that's what you can tell cops
