Re: Correct carb numbers (fatt55)
The only #4223 Holley I recall was an 850 cfm chokeless 4-barrel. It had mechanical secondaries and the accelerator pump nozzles were located in the centerpost. Holley considered this carb design suitable for racing only. In fact, they marketed them in pairs for drag racing with a tunnel ram intake back in the seventies. Yowzah!
