Thanks for the burnout advice
I've heard many theories on engine break in. If it were mine, I'd start it up and drive it normal for a day or two. Feel it out and make sure there's no obvious issues. Then I'd work my way to the top of the tach. Hammer it a little bit at a time. By the end of the 4th day, I'll have slammed it as hard as it's ever gonna get slammed. My car is not my daily driver either. Not sure I'd do it that way if she were my regular ride to work.
I'm pretty sure the NMRA big dawgs aren't doing much of a break in. But then again, they rebuild their motors pretty often. I'd guess on an average that a lot of those guys are rebuilding, or at least re-ringing, every 15-20 miles or so. Maybe less than that.
Sorry my advice probably isn't as helpful as your burnout advice will be, but at least you've got another idea to put into your databank.
