Two people can almost move one with no doors.

I recommend an engine hoist like you mentioned, and someone to stand on the back for counterweight.
Or a comealong hooked to something above works.
Personally I use a chain fall for moving both my engine, transmission, and the cab. I can do it all by myself.
