Dunno, snicklas, suggest you stick your head into the engine compartment from all three angles (above front, above behind, and below) before getting serious about a van. VERY tight fit, and access to nearly anything important is a whole different ball game. The engine sits very low in comparison to the body, which was NOT designed for ease of service. Engine onto frame, then body onto frame.....
BTW, just about head gasket time for me, so out comes the engine (again). NOT for the faint of heart!
