Holley carburetors are widely known for their performance applications. Muscle car enthusiasts have used Holleys on high-performance engines since the early 1960s and are known for their design characteristics, which make them easy to rebuild. Holley has produced many different carburetors over the years which incorporate both two and four-barrel designs. Identification issues include: recognizing Holley carburetors from those manufactured by Carter or Rochester, determining the Holley model in question and differentiating Holley model numbers from the auto maker's part number.
