69RavenConv 286 Report post Posted January 3, 2012 The markings on the horn say its a 3310. From my Holley Carburetor tuning book ... The venerable Holley 3310 dates to 1965, when it was used as an original equipment carburetor on the 425 HP/396 ci Chevrolet. Originally rated at 789 cfm, this carburetor has since been revised several times for universal installations. It is currently rated at 750 cfm. Hope this helps!

1969 Mach1 14 Report post Posted January 3, 2012 The list number 3310 should be a 4150 series 780 cfm vacuum secondary carb. Typically found OEM on some Chevrolets. Fairly sought after carb. They always seem to work well. That plugged vacuum fitting on the throttle linkage side is not supposed to be there. That boss on the main body was for the bell crank pivot on mechanical secondary carbs. If you dig through Holley's web site there is a section with list numbers and the original settings for jets, nozzles etc. as well as the metering block part numbers. That may some additional info for you. Quote Share this post Link to post Share on other sites
