FatTony - I took a screenshot and included it below of your engine in its current home from your Welcome Center post so folks can get an idea of what the current situation looks like.
It looks like it may be a tough cookie to crack in pulling that out. Looking at the picture, I'm not sure you have enough clearance to lift up and out. Definitely not with the bell housing and transmission still attached as there is just not enough clearance through that shoe box opening.
If you do go the up and out route, I would suggest removal of all peripheral components; manifolds, starter, generator, possibly even the distributor and water pump to minimize the engine footprint. I think too you will need to pull the transmission, bellhousing and flywheel (while supporting the engine with your lift, before doing the up and out move.
Perhaps you can provide pictures of the front end of the bus, outside and underneath, to see if there is a way to better access and pull the engine in a different way?
Your engine install is similar to a "Dubl Duti" "Forward Control" deliver van (1951 versions pictured below) and checking on how those are removed may provide some helpful insight.
Others should be along to offer further suggestions soon.
