Radiator recommendations

I am stuck waiting on a tow truck due to an overheating issue. Possibly a stuck thermostat and poor condition radiator. While waiting on the tow truck, I have decided to research a new radiator. The current one is old and seems to have poor flow. What do you all recommend for radiators? I have a 1969 vert with a 302 Holley 4 barrel. Thank you in advance.

I've been running a Champion 3 row core aluminium radiator for several years with no problems.

1967 - 1970 Mustang Aluminum Radiator 22" PS Outlet I have one of these in my 65. What can I say. It cools the car. Electric fans would be nice for traffic though.

Thank you for all your suggestions and help. My radiator is currently a 2 core. My newest question is - should I continue with a 2 core or go to a 3 core? I do not have AC or power steering, and it is a manual transmission. I am clueless about the differences regarding the number of cores needed. Thank you in advance.

Look for a two row with at least 1" cooling tubes. The ACP Max core is a really good radiator also for less money The ECP radiator is a great value. I have the ECP in my cars.

I put the ECP into my 66/302 and it cools it very nicely. I still have an old mechanical flex fan, and it keeps it cool down here in hot a$$ Florida, although i had to make a run for it once when the beach traffic was backed up. I plan to put electric fans on it, but after my long list of things to do on my car. I would HIGHLY recommend this radiator, it matched perfectly into where the old one came out..

There still are a lot of questions you probably know the answer to:

Do you want to keep stock appearance and stock fan/shroud?

Do you want better cooling or was stock size good enough, since you don't even have a/c?

If you go with a stock replacement type with brass cores, you won't find cores larger than 5/8" because brass is too weak to make it 1" like an aluminum ACP, Griffin or Ron Davis. Tests show that 2 cores 1" wide cool better than 3 or 4 little 5/8" cores, lots of theories behind the heat transfer, flow, etc.

I went with a big-block sized Wizard Cooling radiator that has two 1.25" cores and dual Spal brushless (variable speed) fans because I drive in stop-and-go city traffic a lot with a/c. It's got an aftermarket look so even painted black, which I'd never do, it'll still not look stock.

Don't just jump on the electric fan train because most cool worse than the proper mechanical fan and shroud. What's funny is Champion/Northern Radiators are the cheapest radiators out there, with the least expensive epoxy sealed core (as opposed to welded), but I see SO many builders using them, and some are pretty high dollar projects. Kinda blows me away. They say their warranty dept is good too, but I'd rather spend a little more and not have to use the warranty.....

I also bought a cap with a sacrificial zinc anode. Its supposed to keep corrosion from building up due to the coolant going through dissimilar metals.

Thank you for all the info. Until this happened, I didn't have any issues with cooling. Because of this, I don't think I will change the size of the radiator. I believe it is just that the current radiator is finished. I can't tell if it was original to the car. it appears old but that doesn't mean it's original. After reading all of the suggestions and information, I think I am going to go with an aluminum radiator (ACP MaxCore) and use the original shroud. I know the aluminum isn't stock but right now I would like to be able to drive my car worry-free. I appreciate the info about the Spal fans. I have been thinking of installing one due to the stop-and-go traffic but wasn't sure. I really appreciate all the suggestions, tips,help from everyone.
