Does having the timing retarded have as much of an effect on running hot as being too far advanced?

Here is a question that some of these guys might be able to help with. Where is your temp sensor located? I have heard that if it's located in the head you might pick up heat from the headers giving false readings. The increased airflow around everything when going down the road might be partially taking care of what might be a false temp? I have heard the temp variations from having the sensor in a head vs in the intake can be anywhere from 0 to 20 or 30 degrees. I'd really like to hear from someone who has tried a sensor in both locations and what their findings were.

It sounds like you have a good radiator, a good high flow water pump, and a good fan. The only thing you lack is a shroud. Walker has a new 17" Cooling Components fan/shroud combo that requires less clearance than the older Cooling Components fan and it moves a lot of air. I don't think it's in their catalog yet, but they were taking pre-orders at the Nats back in August. My personal experience with going from a Spal fan like you have to a Cooling Components fan/shroud is I run cooler at idle or slow traffic but picked up a few degrees running down the highway, even with the flaps that open up to allow more air through at speed.

You've spent a lot of $$$$ on cooling problems so you might want to buy or borrow a laser temperature gun to verify that you are actually running that hot. That kind of goes back to where the temp sensor is located, if in fact that could be an issue. I wouldn't suspect a gauge problem since the temps go down on the highway, but I'm wondering if the location of your sensor, if it's in the head, is being effected by header heat.
