I have a four barrel Holley that I am trying to identify so that I can buy the necessary rebuild kit (from Holley). I have looked for all of the following numbers on Holley's rebuild kit page and have not found a match. Please let me know if you can identify the model OR direct me to a resource that can help me get the proper Holley rebuild kit.

Markings on upper right choke body:

L15T 3310-3
3100
10569

Thanks for your help!

it's a normal Holley aftermarket carb, a descendent of the original 3310 used on early BB Hi-Perf engines. The reason you're not finding much on it is the mis-spelling in the text.

It's LIST, not LI5T. any of the usual suspect vendors will have a Holley kit for it.

:cool: The Holley "Fast Kit" is: 37-1542, the Holley "Trick Kit" is: 37-933, while you're at it you might want to add the secondary metering block :) 34-6) which will convert this 4160 into a more desireable 4150. The thing I like about the 3310-3 is that it will take an electric choke kit (something the Holley 4346 won't).

Here is an interesting "How To Rebuild It" article: http://www.automedia.com/Building_The_Ultimate_750_Holley_3310/pht200011017h/1

adding the secondary block may require you get a different fuel line. You would also need a set of jets if it doesn't come with any. try 80 or 82. If you decide to go with the block look carefully at the area around the back of your carb, see if there will be any clearance problems related to moving the float bowl back 3/4 inch. Sometimes there's issues with the large vacuum line that goes to the power brake booster.

Mark, it wasn't just "redesignated", it was changed. The new designation was the result of it being changed from a 4150 series to a 4160. Similar? Yes. The same? No.
