Gleslie, George I have gone through the overheating problem for and Alum 427 motor. These are the things I have done to stop the 220f at the track racing.
1st Thermostat, 180F thermostat. The FE one doesn't have enough flow. The housing size is only about 1" for the opening. You should look for an BB dodge thermo for a 440/426. The opening is 1 1/4" where coolant goes through. The thermo stat from Dodge is about 2MM larger. You need to trim it down to fit in your thermostat opening of the manifold. I used a grinder. This should control your over heating. I don't have the part number from Stant. Take your old one to match up. I think the Stant # is either 33036 or 30138. Ask to see them side by side. You will see the differents between the 2. 5 minutes of work, you will be good. Last note, add a 1/8" hole in the housing to help get the air out of the system. Hole to be at top. Rick L.
