I didn't think so.
Just because they got away with it doesn't make it smart. If they've got the deep pockets for that sort of thing, more power to 'em. I expect mine to last for awhile.
No full throttle for the first 500 miles or so.
Vary your engine speed as much as possible while driving for the first couple hundred. By that I mean with load on, not just blipping the throttle.
Take it easy between 500 and 1000 miles...no max RPM runs. 4000 - 5000 tops is ok.
Change the oil at 50 miles, and again at 500, and again at 1000. NO SYNTHETIC OIL DURING BREAK IN!!!!
After 1000, you're good to go.
NEVER, EVER PUT ANY SORT OF OIL ADDITIVE IN YOUR OIL!!!

Ask the guys that say that if they'll pay to fix it when you break it by doing that.

There is not a motor we do that doesn;t see the dyno and max RPM with 20 miles.
-first start we heat cycle, change oil and filter
-take for a short drive and verify the car seems well and check for leaks ( 2nd heat cycle )
We then move to the dyno for another round of heat cycling and different loads to seat the rings. ( 3rd heat cycle )
good cool down
We then start tuning and see max rpm...motors vary from NA 400+ to FI 1000+ rwhp motors.
The car is then checked over again and another oil/filter change is done.
no synthetics
We then recommend oil/filter changes every 500-1000 miles until 3K miles. I change mine every couple times to the track, but that's just me.

I fully realize that you racing engine builders march to a different drummer. That's because you're building to and for a different standard than Joe Lunchbucket does in his garage, nor are you necessarily expecting that it will go for 100k miles before it comes back. One of the commonalities I've seen since I've been posting here is there are lots of kids (apologies to all...my 53 year old perspective), which means limited incomes. They only get to do it once since the deep pockets aren't there yet.

My motor has not seen max RPM yet and has had 3 oil changes so far. I have 503 miles on it since the rebuild. I vary the RPM a lot and give it about 50000-5500 rpm NOT under WOT to seat the rings. For the first 30 miles/30 min of driving I would not drive in the same gear for more than about 30 sec. The first 20-30 miles are when it is most crucial to seat the rings

I told my engine builder that I heard to go wot a few times to seat the rings and he started laughing. He told me the rings would surely be seated but every other break in surface isn't going to like it. That's just what I was told. Personally, I took it easy on mine - I want it to last, not fix stuff all the time.
