Three Chrome 9 Super 7® Carbs to 4-Bbl Intake Manifold Adapter Kit

Experience iconic performance with the Three Chrome 9 Super 7® Carb to 4-Bbl Intake Manifold Adapter Kit. This comprehensive package allows you to seamlessly mount three high-performance 9 Super 7® carburetors onto your existing 4-barrel intake manifold, dramatically enhancing both the aesthetics and power delivery of your engine. The kit is meticulously designed to simplify the transition to a multi-carburetor system, a setup that was once a hallmark of performance vehicles.

The adapter itself is precision-engineered, featuring robust aluminum construction for cooler fuel temperatures and improved efficiency compared to older cast iron designs. It perfectly bridges the gap between your 4-barrel manifold and the three 9 Super 7® carburetors, ensuring a secure and leak-free fit. The kit includes everything needed for installation: the adapter plate, three meticulously crafted 9 Super 7® carburetors (one primary with choke and accelerator pump, and two secondary without), progressive linkage for smooth operation, air cleaners, a fuel block with fittings, and vibrant red fuel line.

This kit offers modern reliability built upon a classic design. The 9 Super 7® carburetors feature updated Grose-style fuel inlet valves, eliminating the common issues associated with older needle and seat setups, and are designed to handle a fuel pressure range of 1.5 to 4 psi with a recommended setting of 2.5 to 3 psi for optimal performance. Extended brass throttle shafts simplify the linkage setup. Please note that a fuel pressure regulator is required to maintain optimal fuel pressure and prevent flooding.

Assembly is required, and careful attention should be paid to distributor clearance. This setup is not compatible with HEI distributors due to space constraints; a smaller diameter-based distributor is recommended. Additionally, the secondary carburetors do not have idle circuits or chokes, meaning all idling functions are managed by the primary center carburetor. Vacuum sources may need to be tapped from the manifold, as the carbs themselves do not include vacuum ports. The total height from the bottom of the adapter to the top of the air cleaners is 11 7/16 inches.
