I have a 22" champion (CC2375) that I have about 200 miles on so far. I have seen several different model numbers installed, most for sale on e-bay are the 26". Mine is top hose on passanger side, lower on driver side. I did paint it black (eastwood radiator paint) so it wouldnt stand out like a sore thumb. I did touch up a few places with some sand paper before I painted due to a few rough spots, as the finish quality isnt up to Be Cool standards (had one in my 69 vette), but with the idea that I was going to paint it I couldnt justify be cool $. My car with the 383 runs at about 190 with a 180 degree thermostat, and knock on wood havent had any issues since, and I did have to drill a hole for the lower passanger side bolt, the other 3 lined up with existing holes. I would buy another unit from them..... If you want some pics let me know what you want to see, as I dont really have any good ones of the radiator on hand....
