I am trying to track down a stock radiator to use the tanks for a core for my 1939 plymouth. I am hoping to avoid paying $700 for an aftermarket aluminum custom job. I have read that with a mild street small block a stock radiator might even be capable of cooling the motor. Personally, I would like to just take a set of stock tanks to a local radiator shop and have one put together.

So will any of the 36-41? radiators interchange?
