@prd2bdf -- I second
@Toolmanmike 's recommendation to consider having your original recored. I have had a 1970 300 TNT engine 's high-performance radiator recored in Indy at a shop recommended by
@david hill, and a "regular" 440 26-incher recored in Rockford at a shop recommended by
@71Polara383. I am happy with both.
If you want your P/N 3673 955 26-inch rad recored, make sure to ask about how many rows you want. Buttercup, my 1972 NYB, was originally built with a 2-row radiator; when getting the latter recored in Rockford, I was asked by the shop owner if I wanted it back as is (2 rows) or a high-performance setup (3 rows). I went with the latter, even though it was almost $200 more, and I have zero regrets: Buttercup's engine performs beautifully in 95F+ weather, with zero heat issue.
PS: it would be great if you would post more photos of your
gorgeous Newport Navajo in the
1973 Chrysler Thread (and the tag too?)
PPS: just noticed that this thread dates back to 2022, so the rad must have been fixed by now. Any chance that you might join the
2024 CATL drive on Sept. 7?
