4. This is the custom-machined inlet and outlet for the radiator.

5. The tranny cooler and oil cooler will also be built-in to save on space. The tranny cooler is the larger unit up top, similar to those found on some GM trucks.

6. Here's a look at one of the two high-performance Perma Cool 14-inch fans to be installed to help with the cooling duties.

7. These are the patterns used to mock up the side tanks. One side is tapered to avoid the mounts for the grille.

8. Here is where the inlet and outlet meet up; in the middle you see the separator. The coolant will go through the inlet and then pass through the radiator twice before exiting from the outlet. The coolant will pass through the chamber that houses the oil and tranny coolers as well.

9. This illustrates the oil and tranny coolers and the start of the end tank that will house them.

10. And here's the radiator all welded up and almost ready to be installed.

11. This is the fan shroud that suspends the two 14-inch Perma Cool fans. They boast 2,950 cfm a piece, which should have no trouble putting a dent in the heat of the coolant. The fans were mounted low on the radiator so you can't see them through the grille shell.

12. Bio figured, why not fab up an overflow tank to complement their radiator? The tank was shaped to be flush mounted into the custom core support. Here is the area they have to work with.

14. The aluminum was drawn to shape and tacked together to check for fitment.

15. This is the finished overflow tank ready for installation.

16. The overflow is a perfect fit and looks right at home in the custom core support.

17. This is the finished results of a lot of intensive labor. The engine couldn't be any cooler unless you threw ice at it.
