Holley Model 0-80870 Street Avenger 870 cfm. Purchased new from Holley in February 2023. Low mileage trying to tune the carburetor. Decided too big for the installation and went with a smaller CFM carb. This 80870 is stock configuration except that the metering blocks were professionally modified to use brass 6-32 plug for the Idle feed restrictors. The IFRs installed are stock size at .036. Comes with a small assortment of other IFR plugs ranging from .034 down to .028.
