A totally correct response.:TU: I forgot to add that Al radiators are lighter weight (25% I think) than their copper/brass counterparts.
radiator My Vortech YS Trimmed 455 runs at 165 degrees all day long with a stock four row and fan clutch. I live in San Diego so it does occasionally get pretty hot. This car also made 814 lbs of torque to the rear wheels about 1 month ago so it is no slouch.
