Removing a 318 from a van

So I’m considering removing a tired 318 from my newly acquired 84 Dodge van.
1st thought was remove radiator and bumper/ grille and slide it out the opening.
2nd thought was take the van off the frame and roll the frame out and work on it like a gentleman. Swap out 904 for an over drive, rip off homemade exhaust for headers and side pipes.
You know - normal Mopar stuff.

Thoughts?
#318willrun got a thought?
