I had Wizard Cooling build me a radiator for my Daytona clone. Have a mild 440 in the car, flexi fan and radiator shroud, 170º t-stat. Have not had a problem yet, was stuck in Friday morning traffic last year at Carlisle for 30 minutes with no issues. My friend who owns a radiator repair shop checked out the radiator and said it was a nice unit.

My Dad always told me, when setting goals " avoid disappointment, aim low".
