Power cords? Burn in? Seating the Pistons? LOL, I love this stuff.
I can't tell you how many times I have seen a performance engine built and tested up to it's estimated RPM limits as soon as it's ready with fluids and exhaust. Never, and I repeat NEVER does anyone talk about a break in period. That's a myth propegated by the manufacturers to help people justify thier expensive purchase. If you buy an M5 BMW you can floor it right off of the dock in Newark, Houston, or Long Beach, it will be just fine, your friends in Bavaria built it that way. Same goes for your Nissan, Caddilac, Corvette, or Porche.
BTW, we have built 550 - 900 HP engines, tested and tuned them at extreamly high RPM's, then dropped them right into the cars to race (strip and road) without any problems at all. No break in required. Most were the same blocks and components that come with your car from the manufacturer just modified with some performance parts, so these are not crazy one of a kind engines.
Watch Horsepower on SpikeTV on the weekends to get an idea of the myth of engine breakin. They start at 5000 rpm runs, and go up after about 30 seconds, that's the breakin.
