Holley Performance Parts and master builder Keith Dorton put their heads together to deliver the next step in carbureted engine performance maximization. The aptly-named Holley Keith Dorton Series Intake Manifold outperforms the closest competition in head-to-head dyno-testing by 25 HP at 7,100 RPM, making it ideal for both oval track and drag strip racers.
Boasting a single-plane design that unlocks superior power in the 4,500 to 8,500 RPM scope, this beauty is compatible with 23° standard-port small-block head applications and classes that require cast-iron heads and un-ported manifolds. It’s fitted with a square bore mounting flange and an isolated water cross-over, with a port size measuring 2”H x 1.20”W and standing 6.13” in both the front and rear.
