That ok I just found 1984 e250 with diesel 6.9 for 500 dollars it run good but look nice it blue.
6.9 Powerstroke is mechanically fuel injected, naturally aspriated and most likely will have trouble getting out of it's own way. Also, prior to 1991 Ford vans were bigger rust buckets than they are now, each and everyone of them had the entire hood rust off all the way to the hinges..............
Keep looking...............remember, not only can you spend to much, you can spend to little..........ya get what you pay for.
Also, FWIW, I have been driving vans since I was 18 or 19, deep down they are really not that enjoyable to drive, I would look for a P/U truck.
