i have a 70 Chrysler Newport with a 383 2bbl. OK it not high HP motor like all the rest of you guys are talking, but when i first got it it would run on the warmer side, 210-220. i went out and bought a new radiator from 1-800-radiators, had it delivered to my house, put it in and now it runs 160-190 depending on the outside temp, 200 deg on 98 deg day with the A/C on.

are you looking for a "numbers" radiator? if not, buy a new replacement and you should have no more problems.
