    1967 carb Quetion

    I have a 427/390 HP. Holley List 3811. Someone told me to check the front metering block #. Mine is 4777. He has a similiar carb and his front metering block# is 4796. Any idea what number should be on the Holley List 3811 carb. Mine is dated December 1966 4th week, which is a correct date code for my engine.

    4796 is the correct metering block for a Holley 3811 carburetor. However, I would not rule out the possibility that 4777 might have also been used, especially early. It's a period-correct metering block number.
