Quick Fuel Technology (QFT) is well known for its innovative high-performance and racing carburetors, and most recently, for its show-winning Black Diamond heat-resistant coatings available on many of its carburetors and new QFI electronic fuel injection. To complete the package, QFT is offering a Black Diamond square bore, four-barrel intake manifold that fits '57-'86 (262-400cid) small-block Chevy engines and those equipped with ‘87-’91 L98 Corvette aluminum cylinder heads (non-EGR applications). In fact, this manifold can fit just about any small block Chevy engine with standard port and bolt-hole configurations. 

The QFT Black Diamond manifold is a dual-plane, 180-degree design intended for hot street performance up to 5500rpm, designed to produce a wide power band and excellent throttle response. The proprietary Black Diamond coating not only lowers inlet temperature by six percent, it provides a tough, scratch-resistant satin black finish that is impervious to fuel and under hood chemicals.
