My '83 351W had a similar problem. After replacing the thermostat, and still had problems warming up, I replaced the thermostat housing itself. Seems that over the years, the pot metal disintigrated and allowed alot of coolant to flow around the new thermostat.
Also, be sure that the thermostat is staying in the small groove. Sometimes, it can move around during installation and cause the problem you are having.
Good luck!

If it didn't need to be there, it wouldn't be there.
It's the ECT sensor. Engine Coolant Temp sensor. The sender that the computer uses is different from the one the dash gauge uses. If you leave it broken off, your computer thinks your engine is always cold when it's not. You will use MUCH more gas, and your exhaust and EGR system will eventually get clogged up with carbon.
Sorry - now that I realize what forum I'm in, is this an EFI truck?

If you have disabled your emission control system, you dont need to worry about the sensor. My '83 has a 2bbl Holley carb, and a DS-2 ignition system without the aid of a dead computer. Runs just fine.
I am glad you got your truck straightened out.

Follow the lines going to and coming from the sensor/switch. More than likely you will end up at the EGR valve, and possibly the distributor. Make sure you are getting vacuum at the dist when you rev the engine or you will notice a difference if you drive it more. Your fuel mileage will be terrible.
