HOLLEY 4 BARREL CARB INFORMATION


LIST NUMBERS AND STOCK JETTING

  
One of the things we noticed over the years is the lack of information concerning Holley List #'s and the specifications for individual carburetors and their stock jetting. Many folks buy a used carburetor at a swap meet or from an ad and find out that it wasn't what they thought they were buying. An 850 cfm "double pumper" turns out to be a 650 cfm with vacuum secondaries. In an effort to help our viewers identify which Holley carb they have or what carburetor they want to buy, we've put this list together. Holley itself has a huge site on the Internet with all of their products listed. Holley can be found at www.holley.com.

Holley also has a catalog of all of their "Performance Products" and services. It is updated yearly. If you need one, contact Holley for a copy. Among many other things, the catalog lists every performance and race carburetor they make and the indivdual specifications for each carb. Such a list would be too big on our website, so we are going to list the most popular Holley four barrel carb List #'s and their cfm size and stock jetting specifications. When you buy a used carburetor always check the jetting. Over time folks are always changing the various parts in a carb and it can be far from the original baseline stock setup. Once you know the baseline setup you can make appropriate changes to improve the carb's performance.

Most square flange Holley carbs have the "List #" stamped on the front, driver's side of the choke horn. Dominator carbs have no choke horn and their list # is stamped on a flat portion of the venturi area on top of the throttle body. The newer "HP" line of four barrel carbs have the "List #" on the driver's side of the throttle body.

Keep in mind that the stock jetting listed is for applications at sea level and at 70 degrees carb inlet air temperature and is meant to give you the baseline calibration. If you live at a higher altitude or in warmer or colder climates, changes can then be made appropriately. Likewise, the power valve calibrations are stock baselines. If you have a longer duration performance or race cam you may need to change the power valves to handle reduced engine vacuum signal to the carb. These carb tuning aspects are discussed on our "HOLLEY TUNING TIPS" webpage.

THE FOLLOWING IS A PARTIAL LIST OF HOLLEY LIST #'S FOR SOME OF THEIR MOST POPULAR CARBRETORS. IT IS NOT A COMPLETE LIST.
