When you come in check the water temp comming out of the raditor. Tire temp gauge or the wife's meat checker will do. If the water is 30-40 degree colder than comming out of the engine, the the problem is in the engine, because the raditor has done every thing it should.

Make sure your belt is not slipping.I run aftermarket pulleys and every six races i change my crank to pump belt.My engine started running hot one weekend and i couldent figure out why, I have an afco radiator aluminum water pump,best of everything in the cooling system.I decided to change the belt and my temp dropped 20 degrees.I dident think about the belt b/c it felt tight but it was slipping at high rpm.Have you tried those neoprene fans,they work the best in my opinion.The deep cups throw some serious air.Hope this helps

I disagree on the above mentioned fan choice. A steel 4 blade is the way to go, make sure your fan isn't backwards. It's got to be something simple that your overlooking, that just heats up to quick unless you have engine problems .
If your running a flex fan throw it in the garbage---that would do it also.

Check your balancer for slippage, timing could be more advanced than you think.
