As for an oil cooler, you want to place that in front of the radiator if possible, not behind. I personally use an RX-7 oil cooler- easy to get on ebay, and super low profile but really thick and handles alot of cooling load- been running on my 4.6 3v for 4 years with oil temps never above 260, even in very hot ambient conditions and 8 hour long endurance races.
I liked that post right until I got to this part. Coyote variants generate a lot of heat over the 3V redline. An oil cooler doesn't need 'first air' which would only reduce your cooling capacity for the coolant side. My 2nd oil cooler is in the front too, but given the space and hood vents, I would certainly choose to put a first cooler in the hood vent. Makes more sense thermodynamically on a race car.
