So the pic shows the t stat backwards . As I thought . I see this type of install on modern autos where the t stat is in the lower hose on occasion .

Tips:

#1. Drill a 1/8-hole on the t-stat flange . Position the hole at the 12 o'clock position at installation to allow trapped air in the engine to vent.

#2. Sometimes the t-stat won't stay put in the recess of the housing and will slip while installing it and not allowing the housing to sit flush against the intake. Here's what ya do..... Apply one small dab of RTV at 90-degree intervals in the recess of the t-stat housing, wait about 10 minutes to let it outgas, and then "glue" the t-stat to the housing (keeping in mind of Tip #1, above). Allow it to cure, typically overnight. Install.

i realize the thermostat was backwards in the pics, i just wanted to show that the recess and the smaller thermostat were a perfect fit.

JEFFFAFA - Im in Tucson, truck hasnt left the garage in 2 years

, but im trying to change that.

As for the housing the 54mm is in the largest recess, only place left would be the O-ring, but im guessing that would cause a leak, and there is no recess on the intake. is there any type of adapter/plate/reducer I can use?

I have seen poor results with the chrome housings with an o ring seal . Seem to not seal properly on old castings . I would use an oe type housing , or a gasket in place of the o ring .

2x for leaking. What, I found it's made from a very soft metal and if it's over tighten a little it trends to bend the bolt ears inwards and causes the o-ring to leak..

Now, I'm using the trouble free steel oem one.

I, had my radiator top tank serviced and they put in a new Thermostat, new hoses.

A week later found, I had a coolant leak some where at higher rpm only.

Okay finally got pissed want to fix it so. I worked the throttle linkage on the carb to about 3000 rpm and out it sprayed some coolant.

I was going to drive it back and show the rad shop what they done.
But it was now leaking to much to make it their so changed it out and said screw it. Plus did not want to loose the coolant.

And...the t/stat is supposed to be installed in the housing with its element facing towards the engine.

1958/64 FE engines only installed in cars, have rounded valve covers without holes for PCV or oil caps. Have an engine oil fill tube at the right front of the block.

I think that is an illusion, it's a aftermarket housing and I only see one recess. That second cut is too deep to be a recess for the t-stat.

Also Bill that intake part # starts with C3 isn't that 63?

The other thing, that intake surface is pretty pitted, I would try and smooth it with somethnk like JB weld and a file, would help make a better seal, and can that oring anyway, go with the stock gasket and aviation permatex. Or what they call high-tach now.

I saw a few yrs back someone had made some out of 1/4" Aluminum heck wouldn't be all that had. Yet could even use a gasket as a template as far as that goes.. And Yup that chrome Thermostat housing only fits the smaller 54mm T-stat

Thanks everyone for the help, I bought this truck to learn on and have as a hobby, and Ive definitely learned a lot, especially with the help from here. I was able to find the housing and the thermostat i need, using a '65 Thunderbird 390 4bbl. Rock Auto has them for a good price now i just have to wait for them to come in!!
