Holley 750cfm Double Pumper Drag Race 4150 Series Rebuilt Ready To Go... on 2040-parts.com

Up for sale i have a Holley carburetor.
This carb has been disassembled, soaked in a cleaning solution then followed by a ultrasonic cleaning, tumbled polished then all passages blown with compressed air.


Choke horn was milled flat to increase cfm to flow 750+ & balance air flow between the primaries & secondaries.
Also note the holes for the choke linkage are epoxied shut to help maintain air pressure once your air filter housing/assembly is installed.

This carb has been rebuilt/refurbished with many new components.
