Just got back from cruising my long dormant street car. Supercharged mild 340, 9.5" PTC 5300 flash, average size trans cooler, generic 2 row aluminum radiator, junkyard electric fan, 4.30 gear, 325/50 radials, 3885lbs with me in it. It's 87 degrees here. Stop and go and a 50 mph cruise. Coolant never went over 195. Trans stayed below 200. Beat on it some to boot.
