First of all, put some properly functioning thermostats in it. You don't say where you are, but I would generally recommend 180 degree units in most cases. These engines, especially the later 8BA's, were designed to run thermostats. The Ford engineers redesigned the cooling system to work more efficiently in these engines, and the thermostats are an integral part of that design. This "no thermostats", "washer" BS had been debunked so many times it would make your head spin. The symptoms your are telling us about are the results of unregulated coolant flow. Thermostats regulate the flow in your engine and are a necessary integral part of the cooling system.

And this is not to mention sludge and crap you are introducing by running it at temperatures well below what it was designed for. 140 degrees is way too cold.
