Factory Cam Break-in
Can't speak for the engine build line as far as run time went, but do know that after installation in the vehicle the run time was less than two minutes in the assembly factory. It involved about one minute to check start, settings, leaks etc and about one minute on the bumpy road rollers. It then took a pedal to the metal trip to the shipping lot and was parked there till loaded on truck or train transports.. None of this time was done for break-in purposes, but rather as a perfunctory engine and chassis test which had to match production line speeds.
They were building 60/hour and had two end-of-line bumpy road rollers, hence the two minutes maximum.
