Rudy,
As everyone knows,radiators take cooling water heat and transfer it to cooler air, keeping the engine from overheating. The more air flow THRU the radiator the better. Shrouds on ALL sides of the radiator are a very good idea. You will derive the best cooling from the airflow entering the front grill area only if that air goes thru the radiator, not around it. Pantera cooling is THE issue of the breed, and everyone has their own 'worked for me' solution. But everyone will agree, the more airflow the better. I would certainly address this area. You may still have other issues to deal with later, but without this one solved, you really haven't taken care of Step 1.
