Mike, I won't doubt your word, but things are looking hot in the picture! That is more engine than what I am using for sure.I may have to give the old original a try. Is yours a 2 row? Thanks, Mark
As most are aware there are several issues that can cause overheating conditions in cars that range from too strong a mix of glycol/water to a bad impeller on the pump, to a bad fan clutch and so on. People are very quick to blame the radiator because that is conventional thinking. And in some cases, the larger capacity radiator just masked a problem that existed elsewhere.
The problem with running a 26" radiator in the 22" support is that unless you cut the support out, you will be blocking the 4" of extra core anyway. Even then, there is no way to properly mount the radiator without some jury rigging.
All things working well, the 22" will be fine. Have the core replaced with a high efficiency unit.

Hi Mike,Even with the 24 inch rad I had to (adjust) the radiator support..It's a 56 Plymouth..It took a ton of modifing just to get that 440 in that car..even more after I installed the f body K frame..I went thru the whole list of things that make it run hot..Shrouds,,different w/pumps,Used the stock oem w/p housing,even different pullys,engine tune etc,,heads and head gaskets.even changed blocks..you name it..30 + years as a Chrysler tech,both auto and marine..This car just wanted more radiator..My problem was hot at speed..I could sit in traffic and run 180..but hit 3000 rpm and boil..It took a while but the 26 inch rad fits nicely..dual fans from a Chrysler LHS are only needed when stopped..

A 22" radiator will do it if it is the same quality as an OEM unit and you don't have low gearing.
The '70 440-6 Sport Fury GTs with 3.23 gears came with a 22" radiator. If they could cool a heavy 440 C body, they should cool a lighter 470 B body. I have a '70 440-6 Bee with the original 22" and 3.23 gears, never had an overheat problem here in FL.
So a 22" in my '68 Coronet with a 440 and 3:91's probally won't work!??

It probably will IF everything is equal or better than OEM. Would Mopar engineer a cooling system that was on the edge? Likely not. There should be a margin of safety in the design to handle 3.91 gears if you cruised at 65mph or less, 75mph maybe not. One thing that we now have that helps cool our old cars they didn't have 40 years ago. E10. If you have your car jetted up for E10, the extra fuel will help cooling at all speeds. Best way to fix a overheating problem without replacing cooling system components, convert the fuel system over to E85.

B5Bee, I have never heard of the '70 440-6 Sport Fury GTs! That sounds interesting. My RR is 3.23 equipped. I have to admit that I didn't consider the rear gear ratio as part of the equation. But,it seems Ma did, as the cars with the optional rears had bigger radiators? Is that correct? Thanks, Mark

As usual, Mike knows what he's talking about. All rads are not created equal and the 26" cure all mentality is prevalent with Mopar guys.
Installing a 26" rad in a 22" car has the issues Mike mentioned above plus if you want it to look original....
Use the 22" tanks with a good high performance core and make sure all the other cooling system components are up to snuff.

Dave, Are the replacement cores 3 row or two? I think the original core in my RR is two row.I know that the spacing of the tubes is different as is the fin count, and tube size. Thanks, Mark

Mentality: There is no replacement for displacement. Even coolant. More is better. Overbuild.

I have ran the champion 3 core aluminum in my cars with no issues.. I have the 26" in place of my 22" in the Challenger with a 512 in it.. No issues and it was a simple as drilling 4 holes and using some 5/16 fuel hose as spacers... Fits like it came thant way. I did not cut the radiator support as it only blocked an inch or so on the sides...
I would never go back to a stock radiator in anything that I was building a non stock motor for. If it was going to be a resto yes.. but not a hot rod... I can get picks if you like...
Here is a general view of it in the car... Want anymore and I can get them.

I have the original 22" rad. in my 68 road runner. It cools the .030 over 383" with out any issues, and there is no fan shroud. I am using the MP clutch fan assy. ( Although it is dangerously close) The new engine is a mild 470" with Eddy heads and hydraulic cam. Anyone using this setup with the a similar low deck stroker? Thanks, Mark
I have had good luck with a 22" rad in front of a 472 CI 658HP Hemi. Hottest it ever got was 185. Depends on a lot of factors (make sure all the air deflectors/hood seals are in place, proper T-stat, good water pump etc.) Make sure the timing is set correctly and you are not running too lean.
I found clutch fans a little tenuous at idle. I went to a solid 16" flex-a-lite fan. Temperature only goes up a few degrees at idle and drops right down once moving. Fan shroud is a must.
