tors including redesigned
fuel bowls with a 30%
increasein capacity, billet
base plates and metering
blocks, a race-only throttle lever, choice of progressive or 1:1 linkage, and dual bolt pattern mounting holes. Main bodies have integrated idle bypass valves and the air bleeds have been moved outward for a smoother transition of air flow. Mechanical secondary carburetors are calibrated for gasoline, and are available in shiny tumble-polished finish with black or red metering blocks and base plates, or anodized Hard Core GrayTM with black metering blocks and base plates all require dual feed fuel lines with 9.75" center distance.
