For peace of mind and a better working environment the engine is coming out.
This sort of reminds me of when I was 18 or 19 and could pull my VW engine in 20 minutes flat. The last time I pulled it was on Redwood Street smack in the middle of Baltimore Maryland. A few of my classmates helped lift the rear end up on some timbers that were being used to build the Baltimore Subway and I then put a piece of cardboard underneath the '68. After unbolting the engine and dropping it onto my chest my buddies grabbed my ankles and pulled me and the engine from beneath the chassis. We then carried the engine into the shop of the engineering school I was attending for overhaul-- ah, those were the days...
