My 67 Dart with a typical built 10.5/1 340 , aluminum heads. I revamped my cooling system this offseason and thought I would get better results but maybe I'm being unrealistic. I have a Champion 3 row aluminum radiator , put all new hoses , Mr. Gasket 160 degree high flow thermostat , offhand I'm not sure of the fan size but its a clutch fan. I also have a 16 inch pusher electric fan for assistance. I have 4.56 gears with a 27 inch rear tire so it revs while cruising. I was cruising in 4th around 2500 to 2700 rpm on a 90 plus degree day with my electric fan on and the car was at it's hottest around 190 deg. I'm just wondering if my setup should be doing better or it's working to its potential? Any info helps. Thank you.
