603, you're sure putting a monster motor in your car and going cheap on a radiator is a BAD idea. Do your research to determine the right style to fit your needs; i.e. cross flow, core size, etc. OR you might want to consider using Evans Waterless Coolant since it has a boiling point af 350°+ and has excellent heat transfer. The stuff is pricey and it is imperative that there is NO water in the system.
Lastly, get a two stage fan for an HO Ford Taurus and use the proper relays to wire it.
My 2¢ worth.
