63 340hp intake 3794129, missing digit? judging?

Oh my gosh. So manifold has to be taken off the car and the splash shield removed? I guess that means the manifold would be judged for part number and appearance and not casting date?

I have the proper part number for the intake on my 63 - 340 but can’t seem to find the date code. Where would it be located? Thanks

Thomas (Peter replied with the same answer as I was typing ,

Don't know about '63s, but my '67 Winters Aluminum 400hp intake date is near the splash shield on the underside (meaning, it has to be off the car to see it).

There were only 2,100 or so '67 400s and my research seems to indicate they were only cast on 3 days. That makes sense for such a low volume because setup of the casting line is not a trivial exercise; so they probably ran a larger number than currently needed and scheduled more as forecasts came in...mine is 3.20.67. I also have a 2nd 400 intake but other than I know it was cast in 1966, I don't remember the casting month and day on that one.

I don't know how many of the '63 intakes in question were made, but there may be only a limited number of dates when they were produced for the same reasons...although, that's all speculation on my part for the '63s...

Hi Thomas. I Believe The Casting Date Is Under The Oil Splash Shield On The Bottom Of The Intake. It Is Held On With Blind Rivets

OH. I didn't realize where it is located when I suggested documenting with pics.

The casting date on 63 340 hp intakes is on the underside and covered by the shield. One of the most interesting aspects of the 3794129 intake is that there are three physically different versions that all share the same part number but are easily identified visually.

The attached picture shows the ‘late’ version from my late car identified by the raised round area located closer to the distributor. The intake pictured in William’s post is the ‘middle’ version where the raised round area is located closer to the carburetor. The earliest version left over from 62 does not have the raised round area at all.

The casting date for my late intake is April and the casting date I have seen for a middle intake was November while the casting dates for the early version go back into 62. Not sure this will make it into a judging manual but can quickly and easily help ballpark the vintage of the intake and whether or not it matches up with the build date of the engine and/or car.

Arland,

Any idea what the purpose of that raised round area was ?

Mark,

Beats me but maybe somebody has the inside info. Seems like there was a theory of being drilled and tapped for something........

That boss can be drilled and taped for manifold vacuum. Not sure about the '63 model but later years that boss was drilled and taped and a fitting was installed for automatic transmission vacuum modulator, power brakes and A/C. Picture below of my '67 with a tee installed for the power brakes and A/C.

Re: 63 340hp intake 3794129, missing digit? judging?

Leif,

That sounds about right and if you consider that the TIMJG looks for 63 A/C to start around VIN 13,000 which was built in April and the casting date for the late manifold starts in April, maybe it provided more clearance from the carburetor for the A/C fitting and hardware. Then again, maybe they are completely unrelated............

Mine is vin 09048. Mid Feb 63 production. Appears to have the middle version of the intake.

I have been trying to upload the pictures of my manifold with the missing "9" and have been unsuccessful. It is dated 9.6.62 and has the following letters next to the date: CM/JG. Not sure if this helps. Thanks

Re: 63 340hp intake 3794129, missing digit? judging?

OK I think I got it. Looks like my manifold is the middle type but still missing the 9

Scott,

My 1st guess is the letters above the date (and upside down) refer to Winters mold and core sets (cope, drag and internal runner cores). Could be something totally different - who knows, eh ?

My 2nd guess is if Bill removes his "missing 9" intake, the date on his will be the same as - or very close to your "missing 9" intake. Time will tell

and for those of you who are collectors and have a spare $5,000 laying around, I thought this eBay post was interesting:
Winters Intake Foundry Snow Flake Very RARE Collectors Foundry Stamp Set

https://www.ebay.com/itm/153489194136

I was kind of amazed at the number of different sizes and shapes. Who knows how many different parts they made and for how many different customers ? - so, maybe their logos were also customer-specific and part-specific dunno ?

PS - Winters Foundry & Machine was founded in 1951 in Canton, Ohio. When Eugene Hervey sold the company in 1969, it was ranked 188th on the Fortune 500 list. Kaiser Aluminum & Chemical bought the place from Whittaker Corp. in 1991 then sold it eight years later -- the plant closed at that time, leaving 170 people without jobs.
