I found a radiator for my 53 flathead. It measures 18" x 18 3/4" the core size is 13" x 18 3/4 and it has 3 rows. It fits perfect behind my grill. My ? is do you think it will be enough to cool it?
Yes, I do. Alot of guys including me are still running the old radiators. Just have it cleaned and pressure checked. Good luck!
