Holley 1904 1-barrel carburetor, list number 3577-2. I am not familiar with all makes and models this fits. Please verify part number and pics match your application. Throttle bore measures 1-7/16" and mounting bolt holes center to center are 2-5/8". Carb core appears to be mostly complete. Linkage moves free. See pics for condition. Core for rebuilding or parts.

Can not be returned if installed, ran or has been taken apart. Must be returned in the same condition as shown.

Please email with any questions before bidding/purchasing.
