I have a 350 cummins low flow that gets hot under a load.

Cummins low flow cooling system diagram. With the cummins system lower air temperatures from the engine aftercooler also means lower water temperatures to the after cooler hence the requirement for low flow cooling lfc radiators. Dept 56 display photos. The low flow system has about a 20 degree drop.

The lower the air inlet temperature the higher the air density hence a more dense charge and improved engine efficiency. The big cam 3 has the low flow cooling system with the 15 radiator hoses and dual thermostats. Air intake system flow diagram.

Low flows were relatively late in the big cam production run. Has new radiator in it runs a little over 200 degrees in a couple of miles. The flow of coolant through the dual valve thermostat 50 is indicated by the arrows shown.
