    Correct Holley Carb for 1967 327/350HP

    In checking specs for the 1967 model year, I understand that I need a Holley model 3310 for the 1967 327/350hp engine. This is type 4160. I have what appears to be a Holley replacement carb on the car. The carb does not have any sight glass window or the ability to adjust the floats externally with the typical screw/nut configuration at the top of the carb. It is not the original carb, but I thought correct for my application.

    Here is the question: my current configuration is a single line feed from the fuel pump with a single inlet into the "radiator-side" of the carb. Is this single feed/single inlet the correct configuration?

    One of the national distributors has new Holley's that are model 3310, type 4160 that has a single line feed from the fuel pump with a DUAL inlet at the front and rear of the carb. Ths unit is new, has the sight glass window, and does have the ability to adjust the floats with the screw/nut set-up at the top of the unit.

    Is the unit on my car a modification of the fuel inlet configuration that was correct for the 1967 327/350?

    Any advice is appreciated.......

    Sal,

    The single inlet on the drivers side front of the carburetor is correct for the 3810 which is the correct carburetor for 300/350 HP cars in 1967. Also,
    the non adjustable float is correct for 1967 small block. What #'s are on the carburetor you are refering too?

      Sounds as if you have the correct configuration. The pic shows a Holley that I took off my 1967 a couple of years, now in basement inventory. I posted the numbers here at that time and was informed that it is a service replacement. As well, the bolts on the bowls are not correct. I can't recall why that is so.

        Is the original spec a 600CFM carb?

        Based upon your advice, what I have appears to be correct since it is a single line feed/single inlet; has non-adjustable floats and no sight glass window. I am not able to get to the car until this evening.

        Last question: I have not taken the carb off the car yet but is this a square or spread bore?

        Thanks for the feedback!

          Bowl bolts should be screws (unique head configuration)

            Paul,

            I also have a service replacement with the same bolt heads as in your picture. As I recall the original bowl bolts had slotted screwdriver type heads.

              Sal,

              Here's the correct carb for your car:


              It is a 3810, this one is dated 751 (67, May, first week). Look for one dated prior to your assembly date not more than six months if you want full points at judging.

              Yes, it has those darn non-externally adjustable float bowls, all of the 67 single carbs had them. The single feed on the driver's side with the internal filter is correct for your car.

              If you want the externally adjustable fuel bowls with the correct metering block and fuel inlet, and don't care about judging, look for a 66 3367. Use a #65 power valve instead of a #85.

              I don't think any of the new generic Holley's have the same fuel inlet and vented primary bowl like the 3810 (and 3367).

                  I found a used one on e-bay a couple months ago for $300. Bought a rebuild kit from Holley and overhauled it myself. It was pretty easy to do. I had to re-adjust the float once on the secondary bowl which is a PITA.

                  I set the mixture, choke, etc. and was of and running great.

                  If you want a perfect looking rebuild, you can send it to Holley and they will do it just like new.

                  Be patient and keep your eyes open. They do show up.

                      Thanks Wayne. Yes, that was the flaw.

                        I'm a minor league version of Joe L. Have some 1967 treasures in stock.
