* Available with either a ball burnished aluminum, polished aluminum, or black aerospace composite fuel bowl
* One-piece air horn assembly with a single fuel inlet
* Torsion spring valve control/adjustment permits seamless primary to secondary throttle response, regardless of the throttle opening rate
* Dual mounting bolt pattern (square bore or spread bore) fits any street 4-barrel intake manifold. Adapter may be required.
* Integrated 700R4/200R4 transmission kickdown cable mounting location
* Ford automatic transmission kickdown
* Inverted flare and 3/8 in. barb fuel inlet fittings
