Dave---A guy over on the HAMB is running what I think is a 34 Ford with the radiator in the trunk area. He pipes water to it with an auxiliary pump, has a louvered trunk lid, and dual pusher fans to pull air from under the car and up thru the radiator. I have seen another with the radiator in the bed of a pickup. I don't know how succesfully they run, but yes, it has been done.
