Thinking of installing one on my 64 chevelle. I want to take the engine driven fan out so i'm looking for something that will be able to keep the car cool in all driving conditions. Anyone have any recommendations on size, type, brand etc....?

Engine is 355 small block, 10:1 compression, auto trans, no a/c. Puts out around 400 horse. Car is street driven (usually hard )

Thanks for the help!!
