That would be a interesting Combo, and I'd go for it since its a 5-Spd MT. I would not recommend it if the donor van had a 4-Spd MT. We had a '81 E-100 with 4.9L I6 and a 4 spd MT w/ OD, and while it got decent MPG ( my dad reports getting 18-20 MPG highway, before the engine rebuild) - BUT it sucked to tow with, and especially pulling our ski boat up the ramp with. I don't know what gears the rear-end had, but we went thru several Clutches over the 15+ years we had it. That was the van I learned to drive a stick on, which was good, because most other MT's are much easier to drive after driving that van,
