440 needs to be Cool

Might check the radiator cap. Had that once. I have a radiator from a international truck in my Duster. Just fits between the frame rails. Had a larger electric fan off some Buick or something. It was cracked in the case, but worked good. Upgraded to a Jegs one that was smaller and not cracked. I haven't proven the fan yet, but I liked the bigger one better. The July 4th parade always took it to the edge.
