    dodge 440 getting hot

    1978 440 eng. In a 69 charger. Bored .030 with flattops. Small Hyd. cam, stock heads. Engine is fresh. Heads are not cracked, gaskets good. Street car. Manual fan, no clutch fan. Champion 4 row aluminum rad. First go round. Now has a champion 2 row. Both have same problem. Coolant only drops avg. 4 degrees as it passes thru. Any ideas? Thanks, kris

    Also had electric fan on 4 row radiator. Do not have it on 2 row. Temp. Still creeps up to 200.

    Install a Flow Kooler pump and 180 thermostat, go back to the 4 row. The coolant is not spending enough time in the radiator.

    Exactly, the 4row has 5/8" tubes. The 2row has 3/4 tubes. Where do I get a flowkooler pump?
