HOLLEY
500 CFM PERFORMANCE 2BBL CARBURETOR
No Choke
Part # 0-80583-1
The 0-80583-1 carburetor shares the hugely successful features of the original 4412 carburetor, but with changes aimed directly at circle track cars. The choke assembly has been removed for unobstructed airflow, utilizes the HP metering block , 30cc accelerator pump, welded throttle lever, screw in air bleeds and stainless throttle plates, plus it has been specially calibrated for circle track racing use. It comes out of the box ready to run with less modifying and less tuning at the track!
Features:
- Gold Dichromate finish for corrosion resistance and classic Holley looks
- Calibrated specifically for circle track use
- No choke for unobstructed airflow
- 30cc accelerator pump for additional fuel under initial acceleration
- HP metering block for improved fuel flow
- Screw in air bleeds for precision tuning capabilities
- Welded throttle lever
- Power valve blow-out protection
- 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
