Just put a 26" 3 row in my 72 Duster. I bought a complete 360 from a guy who was having idleing problems as well as saying it ran hot. I think it may have been an ignition problem but I dropped it in along with the Champion rad and it never goes over 180 without a fan shroud. So I'm very impressed with the cooling. Now the bad... mine came twisted and on recomendation from the seller, I stood on the 2 corners and it did straighten it out. But now that its in the car, it has a slight leak from somewhere in the cooling fins. I'm sending it back for a replacement but it does leak. Overall I'm happy with it, theres always a chance of a defect in anything you buy.
