So i currently have a slant six duster and a 440 waiting to go in. The 440 is from a motorhome so it has "steam holes" and all but my budget is stretching thin and this is where i forgot to dig deep.

The dirt cheapest radiator i can find on summit is a 22" spectra OEM replacement. This is suspect for a 440. Does anyone have an opinion on this radiator with an electric fan? Not racing or using air conditioning, just general road driving.
 
I just use a champion 26" radiator with my 413 big block duster cools just fine and a jaguar short clutch fan, didn't want to mess with electric fans.
 
No clue on aftermarket brands, but even stock 383s, 440s & 440-6 engines came with 22" radiators in muscle cars back in the day if the gear ratio was 3.23 & no AC.
 
Good thing i bought a 3.23 and im too broke to run A/C. This 440 is going to be stock as a rock except a Summit Racing® Classic Cam and Lifter Kits SUM-K6400 cam because i accidently dropped lifters out of the block without seeing where they came from. I always wondered how the late 50s and early 60s cars ran eith 4 blade fans and no shrouds without overheating.
 
How about cuz the compression ratios were in the basement, the carbs were miniscule, the cams were ancient low-rpm technology, the exhaust manifolds tiny, and if the trans was an auto, it often had just two gears, while the manuals were fresh out of farm-equipment, which was all ok, cuz the roads were so poor you couldn't get any speed up anyway..
It is generally written that whatever power comes out of the crank, double that went into heat; Half into the exhaust system and half into the cooling system. If you only have 100 or 150 crank horsepower, the cooling system doesn't need to be real fancy.
But when the engines get to be pumping out 450 at 5500, well now we have a heat problem

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this
more h.p. =more heat
If u need a short jaguar type clucth, I got a brand new one , about 30ish minutes run time on it.
 
We've run small block AC radiators without any difficulty. We've also run cheap aluminum rads.
 
I was having cooling issues with my Stroker motor and got one of the cheap radiators from Summit and man did that make a huge difference. I even think about putting my electric water pump back on as I thought that was suspect. I knew when I put an extra gallon at least of water in the radiator it had so much more capacity and not only that it weighed way less...
 
A slant six radiator to cool a 440? Ain't happenin.
 
I have recently been through this and it can get frustrating . One thing that I cansay for sure is that there is no one way to solve this issue . If your budget is thin , you are not going to be successful . First : you don't need to hack up your ride to fit a 26" radiator . A 22" is fine as long as it is the right one . champion, quick kool or any other is o.k. . Second : you need a high flow water pump and a high flow thermostat . they are not expensive . A clutch fan with an 18" fan or even a 19". Third : very clean water passages in your motor. Forth : 50/50 coolant with water wetter . And , this may not work but this is what others have done . I don't have first hand knowledge of electric water pumps or electric fans but I think they may be of benefit . I have not considered them because the electric system must be upgraded for them to function and I'm totally ignorant of how to do this . In modern cars the water pump , the coolant fans and even the power steering are now electric . Good luck !
 
Unfortunately that was the plan before i got caught up with the flu and missed a week of work so now my budget is about $500 less. Right now im fine with running a stock fan with no clutch just to get the thing running. Champion has this thing which looks decent though.
(66-74) Dodge Dart 22" Core Big Block Radiator
 
Well I just got the 470 back from the Dyno and will need a big radiator. Lucky I have the 26 inch core support so I just ordered the Champion 3 row. Product code 375 FYI. I have used them before with good results. The 68 R/R with a 22 incher cools no problem as long as it is not over 100 like in Reno last summer. Probably will put an electric fan on for those SLOW creeping cruise nites. And a shroud.
 
Mopar Action just did a car with a radiator from Auto City Classics. Maybe give them a call to see what they have for A body cars. Mopar Action was doing a B body car in the article. The radiator looked pretty nice and was fairly inexpensive.

Do you have a source, part number, price etc for these short Jaguar clutch fans?
 
I remember Ehrenberg doing an article on the Jag unit saying it dont have the capacity for the bigger 7 blade fans. It was all we had at the time. Now use the Hayden HD 2947. Rock Auto has themfor about $45.
