I want to get a radiator that cools a little better than what I have now. It's for my Duster with a 440/500, separate trans. cooler, 3,000 cfm fan, Meziere electric pump. The car runs a little hot both driving on the street and waiting in the staging lanes. I'm often at 200-degrees by the time I get to the starting line.

The aluminum radiator I currently have in the car has a 21-inch wide core, 2 inches thick. The width of the radiator opening on the car is about 23 inches (so the current radiator is a bit small for the opening).

I'm wondering what you guys are running? I really don't want to hack up the car by cutting the core support if I don't have to.
