Which Radiator did you go with? I just got my 383 back in my dart and it is still running way too hot. Motor all new, new water pump and housing. Was running hot before the rebuild in town. Car came with a Champion 22 in 3 row radiator and Derale 17" 6 blade fan. Now I need to find a solution that works. 26" seem like it would be tight but may fit? Any further help would be appreciated.
