Improper engine break in.

Built my 360, broke in the cam, changed the oil, stomped the living crap out of it (300ish miles). Pulled the engine to paint engine bay and checked it out for ***** and giggles. Looks like I just built it. haha. Fun times. I believe once you get the rings to seat and cam broken in, it's fair game. Haven't had one come apart on me yet, maybe i'm lucky.
