[87 GT MUSTANG]

i was wondering if anyone knew if there would be any problems with using an electric fan from a truck or high output car on my 87 gt mustang, i am going to the wreckers today to find a fan possibly from a 305 or a 350 since these fans should put out the nescessary air my rad needs to cool it down. I was wondering if maybe my car might run too hot or maybe even too coll which i don't think would be a bad thing.
