650 cfm Holley. Double Pumper mechanical secondaries. It has Provisions for a choke but no choke is installed currently. This carburetor was running on my personal motor. We removed it to test another carburetor. It was dropped and has a crack next to one of the bolt holes on the base plate. The base plate was temporarily swapped and the carburetor reinstalled to ensure that there was no other damage. The damage does not extend into the chambers where the butterflies are. I'm unsure if it can be ran as is. Being sold in as-is condition assuming it needs a base plate.
