Also, this manifold will work with any SBC engine equipped with aftermarket cylinder heads, as long as they have a standard port flange opening and bolt hole locations.
This 180° dual plane intake manifold is designed to provide the best performance for stock to street-performance engine applications to a maximum engine speed of 5500 RPM.
This manifold comes with our exclusive Black Diamond® high temperature coating that is impervious to under hood chemicals and fuels. The black satin finish is highly durable, reduces fuel temperature by 6%, and provides a showroom appearance.
