Cooling, out of options!!!! head gasket ?

a few more tricks for you to try:

1. 160 dgree high flow thermostat

2. drill 1/8 diameter holes ( approx. 6) around the outside of the thermostat you have know to flow more water.

3. make sure you are getting full advance from your distributor while you are at crusing speed. they do go bad. running retarded will cause your motor to run hot.

4. havn't heard of this one until lately at a mustang club meeting, but do you have your front valance on the front of your car. it is the plastic peice under your radiatior. it is perpendicular withthe road and your car. what happens as it is expalined to me is if it is not there, at crusing speed, the air that goes under your car sucks there air out from in front of the radiator and it doesnt go through the radiator, especially on the 79-86 cars.

5. high flow water pump.

good luck i am dealing with something simaliar. and let me know if any of those suggestions helped you and by how much.
