Looking for a 2 groove crank pulley for my 440 motor. Presently running ps on outer goove and WP and Alt on inner groove. My current crank pulley is twin groove 5.2 inch aluminum reduction pulley which I fear is not spinning the WP fast enough to cool the motor in hot days with slow moving or stop and go traffic. My WP pulley is a single groove aluminum 6.6". May consider purchasing both pulleys.
