Finally get to pretend I am one of the cool kids - Holley kit swap

The coolant type oil coolers are pretty common. Vipers use them and I believe the same exact cooler is used on GT40s and other cars. They are nice and small, so pretty easy to mount and you don't have to worry about airflow with them. Maybe not as much cooling potential as an air type, but if it puts up with what Vipers can put out, I'm inclined to believe it's fine. Granted the Viper also has ~11 quarts of oil to dump heat into, so it may not need the same kind of cooling.
