Is this the correct housing for the Gt-500? I see some have it as 8952

The one in the picture looks correct. There is only one type of C7 marked BB thermostat housing used in 67 production.

Thanks Bob, thought it as correct and only C7AE but seeing some posts stating that the 4 digit # was 8952.

I would suggest familiarizing yourself with the other MORE visible aspects of the correct thermostat housing because many times the engineering number is not readable for a variety of reasons. It is mostly only good for naming the thermostat to identify in discussions. Hopefully someone will post a side by side comparison of the C5 marked the C7 and the C8 thermostat. Once you see the visual differences you will understand and it will be hard to make a mistake again. I only have separate pictures and not side by side. Plus it is a pain to post anything on the forum at the moment.

PN is C7AZ-8952-A, the housing is correct in showing the engineering number of 8594-A.

Correct  BG?

Also for 427 Fairlane as well.

You're welcome!
There is at least one other C8 housing that has the casting boss for the vacuum switch, but is not tapped out.  I have one but didn't post a picture.

Yes that is the truck part. That particular C8 thermostat is one that you can grind down and shape the untapped boss area to make a convincing replica of the C7 thermostat.

As you can see that if you take away the boss area material all of the other details look the same as the original C7AE housing . You would want to obscure the C8 in the engineering number while you are shaping the boss area. In DIV II and MCA trailered the numbers are not required although other aspects have to look the part. It is no small job to whittle away that material and shape properly but finding a original can be even harder. ;)

All great info guys. I only knew the engineering # so stock # is the 8952

where might someone find that housing that can be ground down for a reasonable replica of the original?
Title: Re: 67 GT-500 Thermostat Housing

It is a Scott Drake part.

https://www.ebay.com/itm/224700932842?hash=item34513822ea:g:KcIAAOSwHGNhl-aV

It works out well. I did one but can't post pictures.

There is a SD cast into it indicating Scott Drake and the C8 will show when installed as opposed to the C7 part number which is mostly obscured by the radiator hose when installed.

It is a Truck part. You can find them in the same places that other used FE housings ,swap meets ,ebay , used Mustang and Ford parts sellers.

If using the SD repro part to carve out a replica of the C7AE housing it is only logical to remove any SD and the C8 engineering number while you are at it. As if it wouldn't be already evident you would do the same thing on the genuine truck donor part.

I think this the same thermostat housing at NPD that was linked on ebay? https://www.npdlink.com/product/thermostat-housing-water-outlet/208089?backurl=search%2Fproducts%3Fgclid%3DCjwKCAjwxOCRBhA8EiwA0X8hi_GWPmRtIF04ylPg2j91jkFghIjgqxv0bs8KF9stYjYS26pRYETInxoCwKAQAvD_BwE%26search_terms%3Dthermostat%252Bhousing%26top_parent%3D200001%26year%3D&gclid=CjwKCAjwxOCRBhA8EiwA0X8hi_GWPmRtIF04ylPg2j91jkFghIjgqxv0bs8KF9stYjYS26pRYETInxoCwKAQAvD_BwE

If anyone wants to try their hand I have two genuine Ford truck thermostats (which is what the posted link is of)  to start with to make a replica from . A genuine Ford donor makes for a better finished product IMO. PM me if interested.

I'm not arguing, just showing what I did with the Scott Drake. I will remind you what you said about not showing in Div 1 or Thoroughbred, the parts just need to look original and the engineering numbers are not looked at.

When the radiator hose is on that thermostat housing no one is going to see the engineering number.

So to me, this is just taking a different route to get to the same point? Opinions will vary and some opinions apparently are more valuable then others?  Especially to themselves. ::)

Does the Scott Drake thermostat housing have the thumb print size divit at the elbow like the genuine C7 And C8 housings have. I thought that it did but don't see it in your picture. Please confirm that it is there or not. That is one of the distinguishing details . If that is not there you may want to try again.

I figured you would want to know. Without the dimple or thumbprint size divit the Scott Drake repro is just as incorrect as having the incorrect C5AE larger thermostat housing . By contrast a well done replica thermostat starting out with a genuine Ford truck thermostat housing donor will have all of the distinguishing 67 GT500 expected details once installed . 
Title: Re: 67 GT-500 Thermostat Housing
Post by: Bob Gaines on March 24, 2022, 07:33:06 AM
Of course you could always carefully add the the thumbprint detail and what with the other proper details  be all good. ;)

Good to have exactly the right insight into what judges are looking for. You would know what they see.

My SD does not have those indicators today but it might tomorrow.

The truck thermostat housings that I have seen have those indicators but the casting for the vacuum tree is hollow but not threaded and has a plug in it. Some are cast iron?

Maybe I'm looking at the wrong one? Maybe someone could offer me a deal on one now? You never know?

Dont know why the SD housing was even made as its incorrect for all FE motors. The c8ae housing was made the same except for the  most common treaded hole for c8ae vaccum tree and the rarer type not threaded but both are same castings.

At one time SD did make the more correct looking C7AE housing but for some reason discontinued it. +1 I don't understand why SD brought out this current C8AE odd housing as it is not good for anything as is of consequence.

I want to qualify here that when you mention SD, you are talking about Scott Drake and not ShelbyDoug! I get blamed for enough stuff already.

I just got my weekly rating from wifey and as usual it was very unfavorable.

That has become for me a bit like hearing the daily Covid death reports and I've become a little numb to it.

Has anyone been in contact with Chris Brown's son about the reproduction he had in the works? I don't want to call over there. Hopefully someone else already got the information?
