1970 383 Road Runner Radiator?

[moparmusclecars]

What should this car have in it? 26 inch or 22 inch? Auto car. I might go with a 440 in it soon. Where is a good place to buy an aftermarket radiator for these car's?

It could have either. Base was the 22 inch, like my car. 440+6, Hemi, air conditioned cars and if equipped for trailer towing usually all had the larger size. When I swapped the 383 for a 440, the 22 inch still cooled things off just fine.

My 440 car came with a 22”, never any overheating issues.
