This is exactly the original plan I had for my own truck, but the 216 is working out much better than I thought it might, and now I have a backup engine. Also, I had a heckuva time finding a 4BT at this end of the country. I was looking for an early one without the air-to-air intercooler. It would be a perfect swap into my auld girl, and with an NV 5-speed would probably double the fuel mileage, which would be just fine. Now I see there's this one:
