This bus was total junk when it was parked here back in 2003. It didn't get better since then. I need to move it, but that did not go well. I kept thinking that I found a solution, but many things went wrong. I did eventually get the Ford Superduty 534 V-8 running, but moving it was not easy. Here's the website I found that has info on the engine: https://www.macsmotorcitygarage.com/another-forgotten-ford-big-block-the-giant-534-sd-v8/
