Holley announces the release of the new Shadow Black Ceramic Coating option for Street Demon Carburetors and intake manifolds thru Marken Performance.  

   The Shadow Black Ceramic coating finish wraps up the Street Demon line in an aggressive and subtle package that also acts as a barrier to corrosion and heat. Street Demon carburetors are known for their clean looks, ease of use and revolutionary design. This design ensures a stable idle, crisp throttle response, and smooth performance. Their optimized calibrations and dual mounting pattern make them Run-Ready™ for a variety of engines and vehicles.  All of the popular and innovative features associated with these carburetors are included in the Shadow Black version, plus they utilize the Street Demon aerospace composite fuel bowl that keeps fuel up to 20° cooler. They have an integrated fuel bowl/main body with all gaskets above the fuel level to eliminate all potential leak paths. They feature small primary bores with triple stack boosters for excellent fuel economy and throttle response, plus a large Goggle Valve Secondary (GVS™) throttle plate that delivers over twice the airflow of the primaries for increased power.  

   They’re available in both 625 CFM (part # 1901BK) and 750 CFM (part # 1904BK). Holley Street Demon’s have Ford kickdown provisions, GM 700R4/200R4 provisions and available TPS kits for GM 4L60E/4L80E transmissions.  

   

   Black Ceramic coatings also available for Chevy small block intake manifold part # 8150BK, and Ford small block intake # 300-72BK.  Also available on hi-ram EFI intakes.
