I have never bought into that baby it to break in stuff. After the initial start up and run up to temp a couple times. I beat the crap out of it like I stole it. Never had an engine glaze rings.
I work on big diesels and we have people come in all the time after a rebuild with 7 to 10,000 miles on the rebuild with blow by out the butt. Put em on the chassis dyno and load the **** out of it at full power and bam rings break in and the blow by is gone. Don't baby a new engine. Use it like it's gonna be used.
Just my opinion anyways.

Those guys don't putt around for a while, its straight to the strip.
God I remember the days of breaking in flat tappet cams lol.
I've heard a lot of the old school car say the same thing, break it in like you intend to use it.
Well and that makes sense in a race engine too right?

Hard to tell as there are too many variables. But I have been on the tuning side of these builds and there are so many things that can hurt one . From a tuning stand point it is very hard to make a perfect tune on a dyno.
a 5 second dyno pull will not replicate a 9 or 10 second quarter mile pass nor will it truly tell you you have enough fuel pump for the application.
case in point I have made 705 hp to the wheels with a single aem 400 pump at 14 psi boost knowing damn well it won’t make a pass at the track above 11 psi without loosing fuel pressure o E85.
not to mention a cooled down dyno tune with a good fan is to aggressive for a full 3 gear pull on an engine that is hot and been running a hour and is all heat soaked .
tune might be great but that doesn’t mean the end user didn’t use it in a way that the tuner didn’t expect. Especially on pump gas .

You're using the car as intended in its intended environment so there are no surprises.
