There will be other part numbers in controversy with NHRA for use in other GM applications, like the "Dearborn" differential that is reminiscent of the Dearborn HD 3 speed trans that Olds and Pontiac used the latter half of the 1960s. GM marketing doesn't like to use the F word, lol, so they called it the Dearborn transmission.
