Recommended Aftermarket Rad setup for 1970 Dart Swinger

How wide is your radiator core. The issue I had is mine is a 22" wide core, so two 12" fans would not fit. I was advised by Cold Case Radiators that two 10" fans would likely not do the job. I have a big block in my 67 Barracuda and the space between the water pump pulley and the radiator was not deep enough to fit one big fan on a shroud.

I ended up going with a 22" Champion 3-core radiator and shroud from Mancini Racing. Wanted to go Cold Case due to good recommendations on here, but all their radiators that would fit had the overflow going to driver side and I didn't want to have to find a way to wrap it back around to the passenger side where my overflow bottle is. I backed that up with a hi-volume water pump and stat, and stainless Derale performance flex fan (rated to 8000rpm) on a 1/2" spacer. I just put it in this fall, but I can already tell it is working better than my old system.
