on my duster I run the champion 26", with a clutch fan and home made shroud. Never gets hot. I didn't cut the core support, I figured I'd try it without cutting first.

So you have a factory 67 (929), 68 (033), or 69 (065)? If that is the case your radiator should have 1/2" tubes with 3 cores. If is has been recored at some point then it is typical for them to use 3/8" tube cores and they will not cool as well. Send it to Glen Ray Radiator and have them recore it correctly. Had my 033 re-cored this spring. Made a world of difference

Just to beat a dead horse, an aluminum radiator actually cools worse than a brass/copper radiator. The best reason to use and aluminum radiator is for less weight, and most people think they look better. The main reason they have been made of aluminum/plastic since around 1980 is they are MUCH cheaper. I call BS! My last 68 dart, hot 360. Somewhere around 435hp at the flywheel. I could NOT keep it cool at all with MANY different copper/brass radiators, fans, shrouds, pulleys. You name it I tried it with no Difference. I bought a cheap Ebay aluminum radiator, no shroud. It never went above 180 degrees! I'm a believer. I literally tried every combination of parts and couldn't get anything to work. I bolted the aluminum radiator in it with a factory clutch fan and it NEVER ran over 180 again. I drove that car to the nats that year and it was one of those hot weekends and I beat the eyeballs out of it and had ZERO issues. I am talking proven science, not anecdotes, glad it worked for you. I have no idea if what shape the radiators you tried were in, and you probably didn't know either. I put a Champion in a 340 Dart convertible, it was not a bolt-in, had to drill two holes and the quality was not great. Sure it was cheap, that is the point of aluminum radiators. I am sure it worked great, I never drove the car as it was a customer car and he never got back to me after he got it.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

I am sure it worked great, I never drove the car as it was a customer car and he never got back to me after he got it. Every part I tried was Brand new! No used junk, plugged up radiators for me. I'm talking new, never used parts. I tried at least 3 different A-body factory radiators with zero difference. Then I bought 1 more and it was Aluminum and it never heated up again! So much for science. Just FYI, I refuse to use an old or used radiator with any new engine build.
