This single-plane manifold was designed for Chevy big-blocks with rectangular port cylinder heads. It is ideal for 500+ cubic-inches or any big-block drag race engine with high air flow requirements. In dyno testing, Super Victor #2927 outperformed the competition out-of-the-box with just a port match and minor blending of critical surfaces. Super Victor Tall-Deck #2916 can be used on tall-deck (10.2") blocks without manifold spacers and accepts standard height distributors. See Super Victor CNC listings for CNC-ported, ready-to-race versions of these manifolds.
