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

Kelly and I were talking before work on a Friday morning at the dealership. Kelly asked me if I wanted to split the time swapping a junkyard 2.7 on a 2006 Magnum. The service writer had worked out almost 18hrs with the service contract company because the salvage yard "drop in" assembly had a cut harness, broken intake, etc. I told Kelly, " Sure, but we are driving this to lunch at noon." We started at 8am and backed it out of the stall at noon for the noon test drive and lunch.

I wouldn't even think about trying that today.
