I have more than one classic , I use the fan from a Ford Taurus . it pulls air like you wont belive . It pulls 3300 cfm and is a 2 speed . I wired mine with a manual switch for high, low and off . The low side needs a 30 amp relay and the high side needs a 70 amp . Most guys run it with a heat sensitive switch so it come on by itself and switches high and low on its own . If you run one of these you need a alt with a high output and the electric fan has a high amp draw .
