1962 Thermostat Housing Question

[Bill O.]

Seeking your help and advise again, as I didn't find the answer via site search.

My '62 340 got a deduct in Triple Crown Award judging because the housing with the correct number 223 was in a smaller size font thus a service replacement. The TIMJG supports that: "Two different aluminum "housings" are correct. One has raised bosses through which the attaching studs pass; the other has recesses: both have the same casting number. the second type listed is different than a similar later service replacement housing, which has part number digits in 3/32 " size (original digits were 5/32" high)"

My question is whether the housing shown in the attached jpgs is the correct first version referred to as having raised bosses?


Thanks much for your help.

Bill--
That's not a correct piece for a 62.

Re: 1962 Thermostat Housing Question

Bill, Many years ago in the "Restorer" Brian Futo had an article on top water outlets. Later others have submitted articles. There are several variations of water outlets for 62. The one shown in the pic by Roy most likely has the seam going down the center. Dale Pearman liked this outlet and said it was correct on some of the 62's. Some is the key word.
You don't have enough info here. Maybe someone can post a nice pic os the most typical outlet. The correct one has large letters on the outside edge. If you happen to find a NOS one it is most likely a NOSR. Small lettering but otherwise correct. John
P.S. The seamed outlet like Roy's is extremely difficult to find in usuable condition.
The outlet on your car may be one from a steel Chevy. 348 or 409 but I forget.
Two rather rough but correct water outlets on ebay for you to look at. Numbers not visible though and they are pitted. Now Roy's is correct also you know.

If this is a SERVICE replacement thermostat housing, it's a VERY old one. GM ceased to use that style font for the "GM" logo a LONG time ago.

Re: 1962 Thermostat Housing Question

This is getting veeeery interesting...and confusing, tho they say confusion is a higher state of knowledge than ignorance. So, I'm making progress.
I found Brian's article(s) on the NCRS CD '61-'62 titled "1957-62 High-Performance Water Outlets":
1) His research suggests that the pics I attached to my initial post (with the GM letters) were only put on Tonawanda engines..I took those pics from a current eBay auction.
2) He refers to an "interim" design housing from '59-'60 and a "later" design, '60-'62. In photo #8 we see two outlets, with the only apparent difference being the size of the part number around the base. He says the larger part number belongs to the "interim design" period and the smaller size characters to the "later design" period (see #8 below)....???
But the later design is what is on my 340 as we speak and I was told it was not correct for that application. I know I must be missing something here. Have Gracious mercy on me!

Re: 1962 Thermostat Housing Question

There are to many opinions on what is or isn't correct by year and HP,
But this is the vary first design showing the casting seam down the middle and the neck has a thin wall that broke when removing a stuck on hose . I once showed the progression of all designs.

I do not believe that any pic shown on this post so far is correct for any aluminum t-stat housing used in 1962 Corvette production. Best, Dennis

Re: 1962 Thermostat Housing Question

Dennis, I do wish someone here would put up a pic of the correct one. I mean they used it from 59 to 62. Not that big of a deal. Someonehelp this poor guy. Someday I will follor Gary's instructions and learn how to post pics.
Meanwhile why is it old Dale Pearman stated that the seamed outlet was also used on some 62's. I used to dispute him on that subject but have since seen a few junker 62 units come in the door from ebay that do indeed have that seamed outlet. Course that doesn't mean anything but it is interesting. JD

P.S. The seller on ebay pushing the outlet with GM on it as being correct for Corvette is causing the confusion.

Re: 1962 Thermostat Housing Question

Kids Kids! Let's all play nice. In this case Dennis is correct. Here's a couple of shots of an original with the 5/32 high lettering. Rich

Re: 1962 Thermostat Housing Question

For whatever it's worth, my '62 340 hp owned since April 1965, #13078, has the same water neck as in the photos posted above by Roy Braatz. Have absolutely no reason to believe it's not the original as factory installed. Has the seam down the middle and small part numbers on the right side.

Re: 1962 Thermostat Housing Question

Larry--
Roy has two different housings pictured above. If you are referring to the one in his 5:26 PM post, I agree. I have seen several of those that are on unmolested 340 and 360 HP 62's that I have every reason to believe to be original.
