I'll chime in with what I think is the most important part of the break in procedure....don't do anything stressful until the water and oil temps are in the normal operating range. Once everything is warmed up do whatever procedure makes you sleep good at night.

On a brand new car with near zero miles on the odometer, I warm the car up and take it through cycles of loaded acceleration, cruise to cool down and then shut down the beast. Do this 5 or 6 times and call it good. I feel getting the rings to seat is the key to a good break in. Remember, unless you have a major assembly problem, there is no metal to metal contact in a motor. All metal to metal parts should have a film of oil separating them. If not, you have nearly instant galling, scuffing and seizure.

If you pick up a new Viper with 70 miles on it for example, don't worry about how you break it in....it probably already had quite a few full throttle pulls on a cold motor:(

Good luck,
George
