Kirk, as Peter said, the single example of a GT-5 with factory oil cooler I worked on, had about the same size air to oil cooler standing up on a crossmember about a foot behind the water radiator, with no air shrouds in or out, and pathetically small ID steel pipes & hoses feeding it. I doubt if ANY oil cooling resulted.
