Help picking radiator/fan for 440

Hey all, have troubleshot my cooling issues down to the radiator. Currently have a Proform 26” with single electric fan that came in the car with a 360LA, now have a 440. 69 Dart, plans of 550HP, 100% weekend street car, not a daily, not a drag car.

Biggest hurdle is I have 5.25” of room between my support and my water pump pulley. Also my power steering pulley may be an issue.

Cold Case-26”, two row, two 1.25” tubes. But 6.75” with their dual fan and shroud setup. Didn’t give any options on the phone just said it wouldn’t work and that’s it.

ECP-26”, two row, two 1.25” tubes. Not sure on depth, guy I spoke with plain said no where near enough room. He recommended a 16” 3,000cfm Spal pusher fan.

Champion-three row, three .75” tubes. Their dual 12” Spal fans, 3,000 cfm total with shroud will bolt in with my setup, 4.75” deep at the pulley area. Guy was super helpful on the phone too.

Have read that the 2 row 1.25” are the best but I can’t find any fan/shroud setups to work with the 5.25” I have and stay under $800. Leaning towards Champion right now.

Any input would be appreciated.

All the radiators you listed are chinkesium at its finest. Look at something from Cool Craft. They offer radiators from US Radiator at discounted prices. Call them and they can give you what you are looking for. I don't recommend the double or triple flow, just the high efficiency core. Two row. The tubes need to be at least an inch wide. Call and they can give you the details.

This is the aluminum version. They offer brass/copper as well.
