A guy tipped me onto this thread for my own swap. Same basic conversion as im doing, but he went with a nissan LD28 6cyl diesel, and a nissan 5-speed manual. Been up and running for years! Don't know if the owner is a member here, but figured id post the link, his mileage is about 5 over the 4.3 on average it looks like. Nice van
