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

What size water pump? 6 or 8 blade? What temp thermostat?

8 blade pump. 160 degree stat. I did notice that water pump I took out of the 440 to start with had a but smaller blades.

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?

Ok, maybe im missing something here. How does that pump keep coolant in the radiator longer?

Nevermore I follow what you saying now.
