These are sister vocational conventionals that differ mainly in hood length: the 367 stretches about 8 inches longer at a 123-inch BBC to swallow 15-liter engines for the heaviest hauling, while the shorter 365 (about 115-inch BBC) houses smaller-displacement engines for mixer and construction work. Both offer set-forward and set-back front-axle positions so fleets can dial in compliance with state and federal bridge laws.
