A 2-row 1" thick core radiator (either aluminum or brass) sounds kind of thin for a 300 horse engine. Thats the size drag racers use to cut front end weight. Leaning it fwd makes no difference in cooling and the shrouded sucker fans are fine. Assuming that everything else is OK including no air in the system, I'd look at roughly doubling the core thickness. FYI, my car ran to 'Vegas last year at 195-200 degrees with a 190 thermostat. Then I changed it to a 160 thermostat for the 550 mile drive home- at 195-200 degrees. Bottom line- the thermostat point-of-opening does NOT lower the engine temp, at least in my Pantera.
