There's really 2 issues creating the problem from what I can see. Modded, high performance engines create a lot more heat than stock engines (obviously) and also most electric fans will never be able to pull as much CFM as our stock clutch fans. I know some people may not agree with the latter but I would bet on it. This is not the first time I've heard of someone having to go back to the clutch fan. I know my efans are barely keeping things under control once ambient temps go over 100*.

I've got LS1 fans on a 5.3 radiator cooling my 6.0. Never any problems. Just put some thick foam around the fans starting about 4 inches from the bottom and go all the way around until 4 inches from the bottom of the other side. You can use thinner foam to fill in the rest but I just left it alone. This will give an almost air tight seal and also will lift the fans away from the radiator a bit. However if you are towing 6,000#, I don't know what to tell you. Sometimes when my mom's work car breaks down, I tow it back, but it only weighs probably 3800# or so.

ok another question thunder, do u have power drains when ur fans kick on with the a/c because i was again reading up on the fans and people said that the 05 drain more power than the ls1 fans, is that true?
