The Edelbrock Performer Air‑Gap intake manifold for 1955–1986 small‑block Chevrolet engines features an air‑gap design that separates runners from engine heat to deliver a cooler, denser charge for improved street performance from idle to 5,500 rpm. High‑velocity runners enhance throttle response and it accepts both spread‑bore and square‑bore carburetors, making it a popular choice for street rods and machines seeking consistent midrange power and distinctive looks.
