Product Description

HOLLEY 660CFM 4bbl Tunnel Ram Carburettor


The Holley 660 CFM Center Squirter carburetor is just as much at home on a competition vehicle as it is on a show vehicle parading around the fairgrounds.

Designed for 2 x 4 in-line tunnel ram applications, the 0-4224 carburetor features a competition fuel curve to provide safe and reliable horsepower, no choke for improved airflow, 1 to 1 mechanical secondaries for tire turning power and a unique center accelerator pump discharge nozzle for the perfect amount of initial fuel.

  • Gold Dichromate finish for corrosion resistance and classic Holley looks
  • Calibrated for use with a 2x4 intake set-up
  • No choke for unobstructed airflow
  • 1:1 mechanical linkage for awesome tire turning performance
  • 50cc center discharge pump for the right amount of fuel in all four bores under initial acceleration
  • Single feed fuel inlet for easy installation
  • 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
