I have a 1973 with a 400 small block. It's a pickup, not a Blazer, but this applies to both. The gap between my cooling fan and radiator is about 10 inches. This seems a little far away to me. Would I get a little bit better cooling if I installed an electric fan against the radiator, as opposed to a pulley fan on the engine?
