A poster over on the Ford Barn said you have part numbers for a Hayden clutch drive on a Y-block. Hayden catalogue is no help. I have a '55 w/272" and AC. I'm running a stock 3-blade fan now. New 3-row core in radiator. I need more air flow at idle/slow speeds. It hasn't boiled, YET, but gets close to the hot mark idling w/air on. I'm running a '59 distributor w/15 degree initial advance. Any advice appreciated.
