440 Radiator Lower Hose Location

[440 Charger]

Thanks Diesel, your comments about radiators are always very helpful. I appreciate you taking the time to comment on my post. I will make sure to go for a 2 row radiator.

My apps lost on this one must be new ways that suck.

The orientation of that housing is the large hose opening points down, not up. That will have the lower hose coming from the radiator on driver side as that opening will be pointing down towards the driver side.

The long tube for the hose on my housing pictured does not point towards the passenger side? I thought it pointed down to the right (passenger side) looking forward at the engine. Maybe I am not looking at it correctly. Thanks for the comment!

The water pump housings on the 383 will also work on the 440.

Good to know Jerry. Thanks for the help as usual!

I just blew up the pic. It looks like it will point straight down on the passenger side. You are correct, it will be a passenger side lower hose.

To the OP, please do not take any advice on 4/5 row radiators or 3/4 row aluminum. Do some serious research. A 2 row aluminum w 1.25" rows in a 26" radiator cools a 496 w 610hp in 125° heat. I have not used a brass radiator, but my understanding is w modern coring on brass, 3 rows is max and will cool a 440 all day long. After that the radiator is too dense and will not allow air to flow through it efficiently.

Remember.....its not the total horsepower generated by the engine, in this case, your cubic inch/ 610 HP., it is likely that 75-80% of the generated hp propels the car or performs work plus its accessories not all being dumped into the radiator. A cooling system is designed for Btu's not horsepower. Your 610 hp equates to this factor:
Determine the number of HP you want to convert to Btu/Hr. Multiply the number of HP by 2,545 to convert to BTU/hr. So, 610 hp x 2545 = 1,552,450 Btu/hr. This heat exchanger would be roughly the size of the car. And the higher the ambient cooling air temperature the larger the heat exchanger must be. If only 20% of the equilivant hp were converted to waist heat to be dissipated by the radiator, the size would be more manageable. 20% of 610 hp or 0.020 x 1.552,450 Btu/hr = 310,490 Btu/hr waste heat to be exchanged. Most if not all radiator sales organizations always state horsepower not Btu/hr because it sounds better and most buyers like to proclaim their highest peak horsepower produced, mostly for bragging rights, as the peak hp is, in almost all applications, an instantaneous number rather than a average over time figure. Additionally, surface area (fins per inch) of the heat exchanger (radiator) is the most important factor but is not solely detetmined by the tube count or their size, but by many factors, including velocity of the circulated media (coolant)..the faster the better, its specific heat characteristics and the temperature differences between the coolant and the cooling air, and the resultant coolant temperature desired to be achieved. Just a few addition points to ponder. Ask those questions to your proposed heat exchanger supplier.

I'm a bit confused, as I'm not confused at all in my engines cooling requirements no do I require an education in what it takes to cool my engine as I have it well in hand in my 125° neighborhood.

Thanks for confirming! I appreciate the help!

Thanks for the visual. Great tool that I hope other forum members can use if they are unsure!

Looks great! Thank you for the comment and the picture. It is helpful!
