Radiator core addition cost???

I have the 25 inch 2 core in my car, and it cost me $200 to get a third core added.

I have a 180* stat, High volume MP water pump, and 7 blade clutch (A/C fan) with no shroud (for now). It would handle 90* days fine, but our 110 * days were killing it.

Now I have the 3 core, and an oil cooler. Still no shroud. Won't need it in the cooler months while I decide if I'm going to use an electric setup on the car.
