Just about all of the buses, transit and over the road, built in the 50s, 60s and 70s were built by GMC Truck and Coach and all but the smallest, least expensive were Detroit powered. A relatively small number of smaller transit buses were built with Toro Flow engines, either diesel or gasoline, in the 60s and early 70s.
Most built in the 40s used 471s, while most built in the 50s use 671s. The 61/2? redesign used 6V71s for transit busses while over the road jobs used 8V71s.
The transit buses used Hydramatic 2 speed automatic transmissions, while the over the road jobs used mechanical four speeds.
