Even though I am not fond of Wayne, and Wayne never built a very good School Bus body; here is a 1986 Wayne conventional on the International S-Series chassis & cowl with the DT466 diesel engine.

The DT360, DT466, and 9.0 liter V8 diesel engines are the only diesel engines that I prefer in an International chassis.
