1960-66 GMC V-12 Engine

1960-66 GMC V-12 Engine

Forgotten by most is the gasoline V-12 engine made by the GMC Division of General Motors in the mid 1960’s. This very large one piece engine block was made for GMC’s largest trucks. Examples of these vehicles were water carrying fire trucks and off road vehicles such as quarry trucks, which hauled tons of rock. As can be imagined, the pulling power of these trucks must have been at the top of GMC’s fleet.

Unfortunately, due to the weight of the truck and engine, most were sold to metal recyclers when their working days were over. Most of the few remaining V-12 engines are in fire trucks that have been used only during fires or fire training.

The attached photos show a ½ ton 1964 GMC with one of these V-12’s made to fit for display at shows. Owner unknown. What a mechanical project to fit it into a small ½ ton.

As far as gas mileage, we suspect they almost have to pull a gasoline trailer to keep the engine supplied!
