It’s a Mack B81 and it says Thermodye Diesel. Maxiidye engines came out later thanks
Lee, a guy I knew owned&drove Coal Buckets. He had one of the first Gold-Bulldog Macks (then new Maxidyne c. 1968) in the area. It was hard to get used to the idea of a Mack with a (5) speed transmission. Just 5 gears. Period. And you gritted your teeth a little listening to it lug down to almost nothing before the driver would downshift.
