I wouldn't be surprised if most engines actually have some time on them before they were actually installed today. Personally I rarely follow the "break in" past a couple hundred miles and I've yet to see any issue do to it. Could it possibly mean I'll need a rebuild at 250k instead of 300k? Sure, but that would be hard to trace back to break in. That said I'd not take it to 8k.Thanks for posting. I have seen the video before and it really concerns me. 3.5 miles on a new Bullitt, yet the Video shows them turning the engine to 8K. I am just old school and the engine should have a few hundred miles (preferably much more) on it before turning it that much. Even the race engines we built were broken in on an engine stand before putting in the car and those engines were build loose.
