Edelbrock Victor Olds 455 intake manifold is a single-plane Air‑Gap design developed for competition 400–455 big‑block Oldsmobile engines. Port-matched testing showed superior flow compared with many fully ported competitors. With an 8.2" carburetor pad it accepts standard 4150-style square-bore or 4500-series carbs, and its enlarged runner shape and smoother airflow path boost breathing and horsepower in the 4,500–7,500 rpm range.
