In the early days of the automotive performance industry, you either ran what was available, or you fabricated something you thought met your needs. Such needs were the building blocks of this industry, and it was through the efforts of many that we have the automotive aftermarket, but it was through the work of one name in particular to which many in the industry owe a great debt, and that name is Edelbrock.
