Edelbrock® Corporation has seven locations: four in Torrance and three in San Jacinto, California, totaling to over 500,000 square feet. Torrance headquarters include R&D, manufacturing, state-of-the-art testing facilities, advertising, and tech support. The company's Aluminum Foundries are located close by in San Jacinto. In 2008, they added a new Permanent Mold and Heat Treat facility next to the existing sand cast foundry, which has been called "the most state-of-the-art sand cast foundry west of the Mississippi." This investment in American facilities is part of Edelbrock's commitment to "Made in USA" products and performance.
