I found this pressure plot on google for thru hood cooling for oil coolers, but I'm planning for 200mph at somepoint so the through the hood is the safe way, also it adds down force. A jeep xj radiator is about the same size as the front panel, vs cutting a NOS tank to do it renegade style and put it either out the bottom, or get slantnose vent fenders and manifold it out the sides..... But those are the options I've found in my search, good luck!
