Champion radiator for ~500hp small block??

-
My only one complaint with the one in Vixen is, it's somewhat ill fitting compared to the factory radiator. Like someone else already mentioned, the side brackets are welded on too far forward, which throws the core back towards the engine, taking up valuable space in an A body. The other complaint is the inconsistency of which they are made. Most work well, but every once in a while you see where someone gets one that does not flow well and as a result, cools poorly. There are more good there than bad though, by a long shot and I believe they have improved over the years. I have zero complaints about how mine cools. It does a great job.

No disagreement here. But it's hard to complain about a $200 radiator not being a perfect fit in this day and age, there are far more expensive radiators that don't fit any better.

I'm not saying it's right, but I think to get factory level fit you'd need to have a factory radiator re-cored. And you can't do that for $200 anymore either.
 
I've been looking at the Cold Case radiator for my Duster. Anyone have any thoughts about this one?

I experienced the same thing when I picked up a 3 core Champion radiator for my Dart. Very little room between the water pump pulley and the electric fans. I'd like to run a mechanical fan/clutch if possible.

I had a Champion in my 70 Duster and was able to put on a fan (OE style with lots of pitch compared to aftermarket) and the 2947 short Hayden clutch. It fit, but not by much. I modified a shroud I got from Mancini Racing to fit. Cooled just fine. My current Duster has the 3 core Champion radiator with electric fans I modified to fit. Cools a lot better at low speed than my mech fan did. I am using the aftermarket pulley/bracket kit from CVF Racing because I'm using a magnum engine and the OE 1970 alternator/pulley bracket setup would not fit. The water pump pulley came with flat head bolts, and they were needed to clear the fans. Your mileage may vary, of course!

I know, right? Just price one with US Radiator and you'll begin to appreciate Champion. lol

I also bet you had a good little bit of room between the core and the radiator support. That's how mine is. I'm tempted to take to a friend who can TIG and let him relocate the side brackets so the core will be moved toward the front of the car, giving me a little more space.

Just reread this whole thread, guess that I have missed that anyone said the CC281B wouldn't fit, as the number hasn't been mentioned again after post #1. That is all I was trying to say. But as usual......
 
The CC radiators have a very fat core (3" on the one you linked to) so you may have problems with clearance between the core and water pump snout. I sure did, and had to go to a Champion radiator which has a 2.5 core thickness.
Do you know if the brackets are welded to the Cold Case radiator so it positions the core way off the core support like the Champion radiator? Seems like if they welded the brackets on correctly, the extra 1/2" in thickness may not cause any issues.

The brackets are welded on just like the CC radiators are. I guess a radiator shop *could* remove & reweld them. Lot of hassle though...
 
I bought one for the wagon , it bolted right in ..I put AN fittings on it and made this shroud with two fans, hoping it runs cool, haven't really had s chance to experiment with it yet

I went to three, long-standing, highly reputable radiator shops in a quest to make one of those Chinese radiators fit. They all told me they can’t/wont reposition the brackets.

I didn't mean to be snippy, sorry if it came across that way.
I don't know at the moment if it will fit or not, I need to measure my opening. That wasn't the point of the post though. I'm just looking for feedback on the general quality and cooling capacity of this brand and design (two row vs three row, etc). Radiators are generally just a box with some brackets mounted that allow fitment in the car. If the box is essentially the same size on the Chevy application as the Mopar application, I can probably adapt the flanges to fit my car. Or maybe not. Yet to be determined. But from what I've heard here, it sounds like it might be worth pursuing. Probably not the best option, but it will get me going and is better than the undersized, misfit POS that the car came with.

I think all the information shared is relevant. People need to know for instance if the brackets are welded on in the wrong place. Don't you agree?

The measurements on the Cold Case radiators are substantially thicker than the CC374 or KKS374 radiators. I messaged Cold Case about that to get the actual core thickness. I don't know how bad it is for a mechanical fan with the short fan clutch, but I know the Cold Case radiators are an absolute "no-go" for the Contour electric fan set up.

I put a 22" cold case in my 70 duster and tried putting a mech fan/clutch in. Would not fit at all (hit the core). Pulled the rad and went 26" 3 core champion. Worked great with contour fans.

When they sent me the measurements I was surprised. I've seen a few people run them so there has to be a way, but nothing I'd want to run would fit with one of those.
 
I agree RRR. The aluminum radiators do a great job. You do have to admit that it gets old when they say it will fit. Yes, after modification. I had to modify the 26" Champion in my Road Runner, the core and brackets were too wide. No room left to modify the radiator, modify the radiator support. We just have to know what we are getting into.
Good luck with your choices!
 
Why is that?
I sometimes help a friend who owns a high end restoration shop in this county. When I say high end, I mean it. I'm talking about 150K plus builds. The guy is good. We had three different vehicles he ordered Cold Case radiators for. Two 62 Corvettes and a 69 Mustang. None of the radiators fit. Not even close. They were the correct numbers for the application. The Corvette radiators have "nubs" on the bottom tank that fit into holes in the very front cross member. The nubs on both radiators weren't even close to being spaced right to fit. Matt called and they told him they didn't have the correct measurements and that's how they made them. If he wanted them right, he needed to move the nubs and tig them in the right places. Both of those radiators got thrown in the scrap pile and he ordered two more from Griffin. Drop in replacements. The Mustang radiator actually came in damaged with the box perfect in every way. No marks on the outside or inside, so it had to be damaged before they boxed it up. You guess it. They refused to replace it. Also, after that, I called about a radiator for my truck. I never got anyone to answer. I sent messages through here to the Cold Case Rep. I never got an answer so I bought one from Summit. Not a Cold Case, but a Summit brand radiator. Fits good. Cools great. Yall can deal with Cold Case all you want. I'll never try them again. Here's one of the Corvettes. The customer put his own tires and wheels on after delivery.

Here's the 2nd Corvette. I can't show you how it turned out, because he took all the finished pictures off his page. It's tied up in some legal mess he wants to be distanced from. But this car was VERY high end. There was nothing but original Corvette body left. Nothing was left of the original drive train or chassis. Everything was aftermarket. I had mixed feelings about it, because it WAS an original numbers matching 327/340 horse 4 speed car. But the customer wanted a supercharged LS monster. He got one.
