Cast crank 440s need the lower outlet on the passenger side, forged crank on the drivers side,,

Check your new motor to determine outlet position.

The waterpump outlet determines the radiator hose location.. When you swap from cast to forged crank if you keep the waterpump housing you were already running the hose location doesn't change..
69 waterpump is drivers lower, passenger upper as was previously mentioned..

Hmmmmm....

Here's the 22" 053 radiator which was standard with 69 440 HP automatics.

Well yeah the 22" is drivers top & bottom but the hose connections on the engine remain the same & if I were selecting a radiator for a conversion you can be sure it won't be a 22"..

I agree...they do not work the best on hot summer days when you are stuck in traffic. However, I wouldn't cut the support to install a 26" either.

I would be hesitant to change a radiator support on a #s car but the car in question is a 6 cylinder car receiving a 440...

not meaning to hijack but why do some of you guys think a 22"rad wont keep a 440 cool.thats how lots of them came when new and used everyday.with a proper system it works fine.

depends how things are set up. I have a 22" aftermarket aluminum down flow rad that mimics the stock 22" rad. It cools a 658HP 472 Hemi just fine BUT I use a solid 6 blade 16" fan, a shroud, 10.3 to 1 compression, 180 degree milodon thermostate, 50/50 mix Zerex antifreeze and stock ratio pulleys. It never got over 190 in the hottest humidest days. I also have all the hood seals and gravel pan in place. It's also a 4 speed. Proper engine clearances are important. A fresh re-build may run a little warmer until things loosen up. Enough ignition timing and proper fuel mixture are important too.

If you run more compression, or use underdrive pulleys, or go on the high side of the anti freeze mix, run with no shroud, or some of the flex fans out there, you could run into trouble.

Hello! Fairly new to Mopar engines, so don't laugh....but, why does the crank make a difference? I honestly don't know why. Thanks!

Crank doesn't matter.Depends on what water pump housing you have.Lower outlet be could me on the left or right your your choice which one you want to use.

And you average summer ambient temperature runs where??

Never mind I looked it up..
Apr Temp 38 to 62 F
Jul Temp 61 to 86 F
Oct Temp 41 to 65 F
Talk to me when you have a week straight over 105..
