I have champion radiators in 3 of my cars. 2 are race cars, 1 is a cruiser. The race cars have a 4 row and work great for me. The cruiser is a 3 row and also works great. They are good radiators for the money. I have no experience with ECP, but I do like the fact they have that "stock" look to them esp if you'd paint them black. I might of went that route with my cruiser if I had known about them at the time.
