1967 Ford Mustang Engine Swap - Six-To-Eight Engine Swap

The Be Cool aluminum radiator assembly comes just as you see here, with a pair of 11-inch-diameter Spal electric fans to help airflow and cooling efficiency. At a later date, we may go to a high-tech Spal fan controller. The Spal fans also come with relays to protect the switching mechanism.>>>

Cooling
Adding a 390hp small-block and putting it through its paces on a road course generates a major heat load into the cooling system, so we knew our little Mustang was going to need a serious heat exchanger to avoid overheating issues. Be Cool has recently integrated a three-tier radiator selection into its entire line, ranging from an inexpensive generic one-row aluminum radiator all the way up to its top-of-the-line cooling system, which includes a pair of Spal electric fans. We decided to go with a modular system: a 27-inch-wide, two-row, 1-inch-tube aluminum radiator with a pair of 11-inch electric Spal fans and a very elegant aluminum mounting system. This complete package is a bit pricey, but we like the idea of a simple bolt-in system with an electric fan so we don't have to pay a horsepower penalty with a mechanical fan. The radiator required moving the battery to the trunk and relocating the voltage regulator. For less money and a little more fabrication time, you could go with a universal radiator with a traditional engine-driven fan and save a few bucks. The final piece in the cooling system puzzle is an Edelbrock aluminum water pump that is far more efficient than a stock pump, which is what we need once the road course flogging begins. There are two choices for small-block Ford water pumps, since the inlets can be spec'd with either a driver-side or passenger-side inlet, and this must match up with the radiator. We went with the driver-side inlet on the water pump to match the Be Cool radiator.
