I have a Classics Industries OER reproduction replacement radiator in my 70' Charger now due to I was having issues running hot. The longer I drove it the hotter it got. The new radiator solved all of my issues. I can idle in Woodward Dream cruise traffic all day long now. I also had a custom radiator made for my 70' Challenger race/street car. Handles almost 1000 H.P. cruising on the street just fine.
