The reason I asked is I recently put a 400/470 in my Dart but I haven't run it in the car yet . It's only been run for the break-in outside of the car. I have a 22" A-body radiator that I recently had re-cored and upgraded to a three core. I was just wondering if the radiator would likely cool the motor sufficiently or not. There will be no racing going on, just local street driving. I also had installed a 180 degree thermostat in the motor.
I have a 416" small block stroker with 22" radiator with shroud and viscous fan. Radiator is a 4 core cheapy Champion Chinese job. No over heating issues.
A buddy (Troy on Moparts) has two Super Stock Hemi Dart and Barracuda* tributes with 22" radiators. No issues.
472" auto and 528" 4 speed Hemis. Both have stock brass radiators with high density cores (more tube and higher fin count). They have vicous fans but NO shrouds (because factory delivered them that way)
Both radiators done by Glen Ray Radiator. The 528 is Siamese Bore even! No overheating.
*Barracuda sold to Ohio just today.
