When I bought a ’56 Plymouth Belvedere to rebuild, and a second car to use for parts, neither came with a drivetrain or a radiator.

Now it’s time to find a radiator, but stock parts are rare, and likely in need of a re-core.

I had also installed a ’66 318 Poly instead of the 277 it originally came with. The engines are different in that the inlet and outlet are on opposite sides. Since my car is not stock, my first thought was to have a custom aluminum radiator built, but the price was well over $500. Next, I checked Champion and was surprised that they had a listing for the ’55 and ’56 Dodge and Plymouth...and it was on sale for a reasonable $199. 98! I would still have the inlet and outlet problem, and since they charged $100 for each part moved, I was still looking at $400. When I called the salesman, he said he would look for something that wouldn’t require that much custom work.

He was back in a few minutes and told me to check out their part number CC1635 as the dimensions were close. It looked like it would fit, so I ordered one and it arrived in five days. Yesterday I fit checked it and it’s almost perfect, even the mounting brackets! The only thing I had to do is drill one .25 hole in the driver’s side bracket.

Their usage list for that part number includes various Small block A and B body Mopars in years ’63-’67, so if you are facing an expensive repair for your stock radiator and are avoiding an aluminum version for esthetic purposes, you might find a stock Mopar radiator from those more popular years to make a later Poly look closer to stock in your ’55-’56.

For what it’s worth, it has a 3-row core and transmission cooler connections

Good find. I paid twice that to have my OE 56 Dodge rad re-cored.

When I considered doing something similar, I found that a '56 Chevy Truck radiator looked pretty close if you have the outlets swapped, and a '56 Ford truck if you didn't. I don't remember the details of them now, but that's what I remember. I think the truck radiators are a little taller than the A-body version and may fit further down on the support. Fortunately, my original radiator had a trans cooler already installed into it so I didn't have to swap it out or mess with it at all.

I'm not a fan of crossflow radiators in '50's cars. I just don't like the way they look. With an aluminum downflow radiator, you can at least paint it black and make it look more like the original.
