When you make a powerful engine you call it a Super Duty
The term “Super Duty” was coined in the early 1960’s by all major accounts. It is a term that was used to describe cars that were manufactured by car companies for vehicles manufactured as factory manufactured race cars. These race cars possessed experimental parts like headers and intake manifolds ideally to expand the boundaries of our ability to drive fast with precision. They were used extensively in NASCAR stock racing competitions and drag racing competitions. The term has been applied to vehicles that were used in race competitions or could be used in race competitions. These vehicles had engines that were designed for performance and speed.
The major differences between a “Super Duty” and a standard vehicle of that same time period are aligned with the engine components and exhaust systems. These engines possessed stronger cylinder blocks which included 4-bolt main bearing for improved strength to stabilize the V-8 engines found in the Super Duty vehicles. The engines were rated at 310 horsepower possessing valves and crankshafts which supported the engine size and capabilities which were available to it.
The “Super Duty” competed directly with the “HO” or “High Output” vehicles manufactured in their day. The “HO” contained a four-barrel carburetor, dual exhaust, and higher compression. It was able to run at 280 hp. Both vehicles had emission concerns which impacted their production. There is no doubt that these vehicles had power and were able to perform at the level of a race car with speed and performance.
Pontiac intended to innovate the design of the “Super Duty” to capitalize on improved combustion chambers, by using cast iron cylinder heads and a cast iron block. Pontiac wanted to improve on the conventional shaft by using rocker arms on ball pivots to allow more consistent valve action which would improve the overall performance. The early years of the “SD” or “Super Duty” made the engineers look at improving the overall engine design to include looking at the cooling of the system which impacted the design of the engine. Engine design was improved over the years to include changes to the cooling system and the placement of the water pump and power steering pumps. The “Super Duty” vehicles paved the way for performance engines and vehicles to have improved camshafts, cooling systems and water pumps which can affect their lifespan and longevity.
