Official Release

PROFORM’S NEW LIGHTWEIGHT ALL ALUMINUM STREET SERIES CARBURETORS!

Roseville, MI: Proform/Specialty Auto Parts, U.S.A., Inc., has just introduced their comprehensive line of ready to run all aluminum Street Series carburetors. Mechanical secondary carbs with electric choke are available in 600-CFM (#67254), 650-CFM (#67255) and 750-CFM (#67257). Vacuum secondary carbs with electric choke are available in 570-CFM (#67253), 670-CFM (#67256) and 770-CFM (#67258). Each Proform aluminum Street Series carb includes metering blocks pre-calibrated for today’s performance engines. These carburetors, while lighter than the street carb competition, are still far more affordable.

These all new carburetors feature changeable idle air bleeds for easy calibration changes if needed. Four corner idle on mechanical secondary carbs help fine tune engines with aggressive camshaft profiles, and the changeable idle feed restrictions further expand idle adjustment capabilities. Service and tuning components are available from most performance parts retail outlets.

These lightweight carburetors also feature aluminum float bowls with fuel level windows, so float level changes do not require the removal of the sight plug. The bowls come with 3/8-inch inverted flare fuel inlet fittings which will accept all conventional dual feed fuel lines compatible with Holley® four-barrel carbs.
