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

Way back when I was into Corvairs, I could replace a throwing bearing in a half hour. By myself, not rushing, using stands, hand tools, and a cheap floor jack. Would have been quicker had I rushed and not stopped to drink a can of root beer, but I was working in my parents' driveway, under the Tennessee summer sun.

A rear main seal took about 45 minutes.

Later, when I was a tech at an MB/Porsche dealership, it usually took me an hour to drop the engine from a 911, which were all air-cooled at the time. Sure, I had air tools, but I didn't like using them on aluminum.

Haven't done my Dart yet, but that's coming.
