crenwelge, Was the 478 factory original in that truck? If I was, was the truck actually an 8500 Series?
Also, I agree that the Fire Trucks were the biggest user of the V-8 637. I had one of the only ones that I know of that wasn't a Fire Truck. As many know, it was a '71 9500 Conv Cab Tandem, with a 20 Ft Flat Bed Dump. It is also the only 637 that I know of that had a 10-Speed Road Ranger behind it. I didn't hate the engine, but I always wished the company I worked for ordered it with a 6-71 or at least a 6V-53 Detroit.
