I used to build a lot of engines for local racers when I worked at the motorcycle shop. I am talking 450's and 250's with 10-12k in parts and head work. They got a few heat cycles, a torque check, a quick blast out back, and were promptly smashed on  Engines with steel liners where given a little more intensive break-in, but not much. |
It's 500 not several thousand and not sure if motorcycles with random mechanics will transfer to cars straight across the board. I would err on the side of being conservative with an expensive machine. Much more solid info on proper break in than info to the contrary.
