What is now known as "STP" was invented by German scientists during WWII as a response to Germany's need for lubrication of the German war-machine vehicles. WWII US Army divisions in Africa that overtook German Afrika Korps vehicles alleged that the Germans employed an engine oil that is now known as STP formulation full-strength in their air-cooled 4-cylinder engines, which successfully traveled through the hot African Desert war-front without seizing due to friction and extreme heat. How the Germans' original chemical synthesis formulation found its way to the U.S. after WWII is not known, but most likely it made that journey along with many of the other German innovations through the distribution of technology through the spoils of war.

Back in the late '50s, hot rodders were increasingly attracted to newer cars making their way into junkyards, or more specifically, the OHV V8 engines they brought with them. An engine that made more power than their flathead V8's, was all too enticing, though the swap wasn't exactly straight forward. Of course, hot rodders were an ingenious bunch, and came up with all kinds of mounting solutions, but none of them were exactly great (or safe). Seeing a need, Hurst came out with their Adjusta-Torque engine conversion mount in 1960, promising a true bolt on solution for OHV engine swaps.

The Bunnell Motor Company was founded in the '30s in Bunnell, Florida as an engine repair and rebuild shop. W. H. Atkinson II purchased the business in 1943, keeping things business as usual for a while, but his interest in stock car racing saw Bunnell Motor Company begin offering some high performance engines as a way to be a part of the stock car racing scene. By the early '50s, his son W. H. Atkinson III was getting into racing, and of course, it was one of dad's engines that powered his race car. By the late '50s, Bunnell Motor Company was focused almost entirely on stock car and drag racing engines, and after his dad died in 1962, Atkinson III had Bunnell Motor Company exclusively building high performance engines.
