FAQ:

Q: What kind of Double Pumper does Holley use?

A: 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.

Q: How to contact Holley carburetor parts and components?

A: 1-866-464-6553. Holley offers a wide variety of replacement and performance enhancing components for your Carburetor. From replacement fuel bowls to power valves and jets and everything thing in between.

Q: Where do you find the list number on a Holley?

A: You’ll learn the key to figuring out exactly what carb you have: the list number. It’s like a “VIN” for your carburetor and should be hand-stamped on the front of the choke tower to the right of the vent tube on most typical Holley carbs. The list number typically is four to six digits long and may or may not have a suffix number behind it.

Q: Where is the list # on a Holley choke horn?

A: 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.
