Description

The place was Columbus, Ohio in 1992 at the Nationals. Indy introduced the 440-1 head and manifold combination that soon became the most popular power for the 440 Wedge engine. With the newly designed heart shaped combustion chamber, it’s still the best selling package at Indy, transforming power deprived combinations into serious street/strip machines.

The best use of the 440-1 is a 451″ to 540″ bracket engine. This head makes the engine perfect for the serious bracket racer… 650HP to 850HP engines with a single carburetor that produces great torque and low shift points. Purchase a complete kit for correct engineered compatibility.
