What is your fastest time to pull an engine, install another and drive it away?

Flat Rate should be illegal. I have always said this, always. Flat rate is a BS "chosen one" scheme that works a man to death, J.Rob
I've been down this road before, but that's another story.
Anyway a friend of mine worked flat rate in a dealer. As soon as they worked out he was good and fast, they sent every crap job his way that didn't allow enough hours.
So he walked away from it and has never gone back to that type of work again.
He used to call it slave rate..
