Hi everyone, am replacing the 250 inline six in this truck with a stock 400 small block chevy.

The guy that built my radiator said that the radiator would cool a 454 big block so Im good on that account.

I plan to run an electric cooling fan along with the belt driven one.

My question is - Do electric fans work better on the outside of the radiator or behind the radiator on the inside?

Any suggestions or favorite name brands anyone would recommend?



Thanks for the help:
