Over Heating Issues - I think!
Over the winter I put aluminum heads on the car, aluminum radiator and dual spalls(also removed the heater hoses...its quite hot enuff around here in the spring/summer).
I am in the process of getting it running ready to go to the body shop and it seems to be getting warm very quickly, on the autometer temp gauge it is reading 200 degrees after running for less than 5 minutes.
I have the autometer sender in the drivers side head, stainless upper and radiator hoses and it seems that the top hose is getting warm as is that side of the radiator and the radiator gets colder towards the passenger side (one of the spals is running constantly for some reason, I guess I wired the programable controller incorrectly) so that may account for the cooling.
The lower hose is cool..........sooooo is this maybe the thermostat stuck?? temp gauge not reading right???
any ideas?

Does sound like a stuck thermostadt. I'd first check to see if the coolant level is completely full since you could possibly have some air in there.
Here's what I do when filling the radiator. Start with a cold engine and pull off the rad cap. Start the engine and let it start warming up. As the engine warm up you'll see that it will start pulling down the coolant level as the thermostadt starts opening. As the car warms up, keep adding fluid until it will not take any more and just starts to push back out the excess. Replace the rad cap and you should be done.
If this trick of filling the radiator doesn't help you then pull the thermostadt and check it by putting it in a sauce pan full of water. Use a candy thermometer to see how hot the water has to get before (and if) the thermostadt starts to open. If it is for example a 180* thermostad, then it should at least start to open by 180*. Of course only use the method if you get your wife's permission to use the kitchen.

Well I took the top radiator hose off and there was no coolant in there....I would have expected some, considering its the flexable stainless type. I had drilled a small hol ein the thermostat before, so there was a little fluid around the thermostat itself...So I guess I will invest in a new thermostat.

your clue was no juice in the upper hose, you have air in the system. You drilled a hole in the t-stat, the purpose of doing that is to get the air out of the system, where does the air go? thru the upper hose and back to the radiator. Use Marshrats procedure and you will be ok. The reason the temp shoots up quickly is not because the motor is getting hot, its because there is air in the water jacket in the heads (where the temp sensor is)

Going try a new thermostat when I ge home tonight...fill as per the above instructions (I could only see a small amount of fluid running across the radiator before (probably from a) the pressure or b) from what could get through the little hole in the thermostsat).......see what happens.
