Radiator tips for 67 Dart with 440

Just because they are the latest "hot ticket" doesn't mean they are the correct part for the application.

If the temp goes up to 220 while driving 35 mph there is a problem with water flow, or air flow, etc.

The fan will only be of any use at idle or really slow speeds.

That is understandable. He is guaranteed to get hot in town driving and at a stand still. Highway he gets himself around somewhat ok. For example a 20 mile drive via highway with a couple stop signs. He sometimes has to stop and let it cool once or twice. Depending on the temps. Obviously a 90° is tough on most hot rods.
I have learned a radiator is kind of a to each their own topic. Some only like the old brass and some only want an aluminum. 2, 3, or 4 core is the next side of it. I haven’t had too many issues with my 22” Champion and mechanical fan with no shroud. Now that I have my low deck 512 in. It seems to run quite a bit warmer than the mild 440 did. Which makes me wonder if I need to get a shroud and/or a different radiator. The shroud will be the first change for me.

He does plan to pull the housing off to make sure it is plugged at all, I think he already has a “better” than factory water pump, and ofcourse who knows how good the radiator is truly flowing.




it’s just finding enough success stories to make him feel comfortable spending the money on one. Lol. Hopefully he can find that here.
