ademon OP master A Joined: Sep 2004 Posts: 6,906 IL, Aurora	I have a the original 22" 3 core max cooling radiator for my 71 demon, but I'm wondering when I go to a 426" or so, 500HP is this going to keep it cool or do I have it recored with more fins per inch? What have you seen with your strokers and 22" radiators? I don't want to cut it up for a 26". Thanks

If you were living in Phoenix Arizona and had Air Conditioning and towing a trailer the answer might be different. All else equal, it would be nice to swap in a 26-inch radiator, but I can understand your not wanting to cut a larger hole in your radiator support. Some things to consider.... Do you have enough airflow generated by your cooling fan? If you have an automatic transmission, do you have a separate transmission oil cooler? Will you have a larger capacity engine oil pan? That should help too. Also, do you or will you have a well designed radiator shroud? A 4-core radiator might help too. Greater capacity, yet some argue that efficiency decreases as you go from 3 to 4 core thickness. Some advocate Aluminum versus original Brass radiator construction as being more efficient as well.

Those who would have you believe that want to sell you a radiator. The only thing aluminum does better is to reduce weight. Call Glen-Ray Radiator and talk with Bob, he will tell you what you will need. The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it. JB Rhinehart, Realist A-Body's RULE!

I had the radiator re-cored at my local radiator shop with standard replacement material. I run an electric fan that really is not rated at a high enough cfm for my set up. Most of the time in the heat my car runs right around 200 degrees or a touch below. In close to 100 degree heat driving in stop and go traffic the temp will get to 208 tops. My car makes 425hp and 520 ft lbs.

If your going endurance racing you need much more. Burning fuel makes the heat... When I'm out at Willow Springs running lap after lap I don't have any cooling issues. There is so much airflow it cools well. But if it's 95 degrees out and I'm stuck in a LA traffic jam moving 1/4 miles in 15 mins, it will get up to 190. I have a champion 4 core, with shroud and viscous jag clutch. I don't run anti freeze though, just Justice Brothers Radiator Cool Additive and distilled water.

By Max Cooling Specs, do you mean tighter fin count. I think Troy did that with a tighter fin count in his 472 Hemi Dart stroker with a stock 67-69 A-body radiator. He's not running a shroud and runs an OE viscous fan clutch. He doesn't have any issues. Hemi hood scoop might help cooling?

Maybe max cooling was the wrong word, I have the "976" radiator, it's a stock three core 22" that was found in some 71 340's.

That all being said what you need to concern yourself about is HP, the radiator does not care if you have a turbo 2.0L, a stroked 360 or a 440 all putting out 500hp, all it cares about is heat and that is a function of HP. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Call Glen-Ray Radiator and talk with Bob, he will tell you what you will need. I basically have the same setup Scott has and it works just fine. Honestly this whole 22" vs. 26" thing is a Mopar only concept; in brand X land the rads are the same size and differ in the number of rows. I'd bet that my recored 3 row 22" cools better than a factory 26" 2 row....and I didn't have to cut my rad support on my #'s six pack car, nor do I have to use an aluminum rad that looks completely out of place.

I first successfully ran a 22" copper 3 row and shroud with my 440. When I added the blower, for space reasons, I switched to a 22" aluminum 2 row and single pusher fan. It runs cooler than the copper unit.
