Hi guys,

Thank you for your input.  It seams the only artifacts that have "S&C FORD" are the license plate inserts and frames.  All the documents above, postcard and September 1966 letter and the documents shown on webpage "The Best 1968 Shelby Webpage!!!" all show the "S&C Motors".  There is even one license plate frame shown on the webpage with "S&C Motors".  These documents are very cool and I appreciate them being shared.  I have studied them and find no clues to determine from them when the "S&C FORD" name was adopted.  So the time period mystery continues.

The only clue that I have is the blue insert and frame that is photographed above, came on a 1966 GT350 that was purchased new at S&C Motors and both the insert and frame  have been with the car every time it has traded caretakers.  So the assumption is that they were on the care when new, making them at least 1966.

Thank you

Cory

Hi all,

If you have a Vintage photograph from S&C Motors that has one of these plate inserts on it, please share on this thread. That image might help establish a time period for these inserts.
Thank you

I have heard from Carl's Ford Parts that Blue Thunder is no longer selling to their retailers.  They are now selling direct to the consumer via the Internet and a popular auction site. I believe their user name is "bluethunderproducts".  I also found a username called "Classic Blue Performance". What have others heard?  Am I mistaken?

Hi Coralsnake,

I found your Internet webpage on S&C Motors and the history they had with Shelby American. I was hoping I would see some comments from you on the time period of each of these Licence Plate inserts.  Do you have any ideas on these inserts?

Thanks

Hi all,

Attached are three S&C Ford license plate frame inserts.  I have tried searching the web for what year each version was used, but with no success.  Who has a idea when each version was used?  I believe they are listed in order, from oldest to later.

1) Red Text, two lines, in large plain text "S&C FORD", in much smaller text all caps "SAN FRANCISCO"
2) Blue Text, two lines large and fancier test "S&C FORD", second line "of San Francisco"
3) Red text for "S&C", Ford script in the blue oval, over the San Fransisco bridge with "SAN FRANCISCO" under the bridge place on a banner.  I have been told, this version is the early 1980's.

Also, does anyone know what year when S&C changed the marketing name from "S&C Motors Inc." to "S&C Ford"?  The internet says they did not change their official corporate name.

Last, there seam to be two versions of the "S&C Ford" license plate frame, one red and one blue (shown).  Is one earlier than the other?  Do you know the years?

Thanks

Cory

Hi Robert, your 721 date code carb should work the same as the original carb.  The best tri-y's might be Scott Fuller.  Very spendy.  Shelby Parts and Restoration may still have them.

The SAI part number will be S2MS-9510-A.  The Holley LIST number will be 3259 or 3259-1.  The early carb will not have the SAI part number, but just the Holley LIST number. The carb below came on an early November San Jose built car with a October 24 engine assembly date.  Getting one with an applicable date code will cost a little more.  Best of luck.

Do you have the San Jose estimated scheduled build date?  I would gestimate mid September 1965.   Looks like SAI shipped 6S366 on December 28, 1965.  The date code for your carb will start with the "5" for the year and for month likely "7" for July, "8" for August, "9" for September.  But as info "O" for October,"A" for November and "B" for December.  The last character is the week in that corresponding month.

Assuming the original block is still with the car, the engine assembly date should get you closer to narrowing in on a carb date.

1966 Shelby GT350/GT350H / Re: Header Gasket
July 26, 2026, 04:40:03 PM
I think we have a winner. Check out the side by side comparison in the attached image.  The dark grey gasket is from an early SAI catalog advertising the Tri-Y headers, the image stretched to adjust the skewed image back into a plan view perspective. The whitish gasket is from 6S1014.  Likely a serviced part that was installed for a short time and then removed for an unknown reason.  It is amazing that it still exist.  I'm convince that the whitish gasket is identical to the OEM gaskets installed at Shelby American.

Take care

Hi all

Another SAAC member sent me photographs of some white header gaskets that were found in the trunk of 6S1014. What do you think? Do they look OEM? Or aftermarket?

Thanks

Appeals / Re: Shelby 66 gt350 block value

Hi Norcal607,

Are you in it to make a few bucks or just break even?  IIRC, just caps could be between $500 and $800.  A regular rebuildable 289 block, $200 to $500.  Matching VIN and date codes, extra, $2500.  So, somewhere between what you have in it and $2500.  A few years ago, a picked up a k-code long block, with VIN for $5000.  You can always sell off the pieces to make up the difference.

Best of luck

Cory

1966 Shelby GT350/GT350H / T10-M1 best gear oil 90W
June 30, 2026, 09:59:10 PM
Hi all,

I am refilling the BW T10-M1 with new gear oil.  The owner's manual says 3.5 pints and to use 90W, mild to extreme pressure-M568-D. When filling, I was only able to get 3 pints in.  So just for grins, I check with the internet on best way to fill and what I learned was to only use GL-4 80W-90 gear oil.  It turns out I put in GL-5 80W-90. The info I am getting and confirmed with the NAPA guy, the GL-5 is corrosive on the brass synchro's and should not be used on our older transmissions.  I have drained it out.  Ugh.  Now I am looking for the correct GL-4 80W-90 gear oil, but none of the retailers stock, so I am having to go mail order or special order.

Do you have a recommended brand, old school gear oil 90W?  I want to stay away from synthetic and used regular gear oil, just like back in the day.

Thanks

Cory
