Just completed one.
Primed, started, cam run in. Cooled down, cut the filter, OK. New filter,out to the road. Drove several miles, checked for leaks, etc. GTG.
Put some mild boost to it, {10-14#}, 3-4 times, drove another 10 mi.
While still hot, dropped the oil, filter cut, all looks GTG.
Drive it.
Not sure where the 500 mi, no power driving comes from, other than 25 yrs ago, before ring technology improved to where it is, today.
When we have dyno access, it's a 20 min run in at 10% load, varying rpm.
Cool down, check it out, cut the filter.
A couple short pulls, then it's hammer time! If the rings haven't seated by then, 500-1000 mi won't do it, either.
1 other item I do: If the exh has been ceramic coated, I wipe it down w/ denatured alcohol, to get grease, fingerprints, off. I also run a fan in ft of the bumper, to force air over the headers. This pretty much cures the fresh coating.
