This is a Holley 3811 carburetor. The date is 673. This decodes as the 3rd week of July, 1966. Perfect for an early Camaro L78 or 427/390HP Vette. Looks clean and complete. The rear vent tube boss had a part broken off and epoxied back into place. It has the correct metering block. Missing choke pull off and other misc. choke parts. Very hard to find carb. $925
