break in oil and changes

I have been building engines on/off for the past 39 years, I worked in the Engineering Lab at Waukesha Engine where we did alot of oil testing, Shell and Mobil oils always came out on top. On my recent 340 roller build I used Valvoline VR1 Racing oil 10W-30 it comes ZDDP enriched. Engine was broke in on a dyno and now has its first 100 miles on the road all appears OK. Please note that the oil and filter were changed after the dyno run.
I refreshed it with the same oil and now plan on changing it after 500 miles. This is a street car producing 442 corrected HP I like the added protection that the ZDDP provides for the long haul.
If this were a racing application I would do some thing different.
I cant see how you could go wrong with a good quality natural API oil with ZDDP.
