1965 K Code Fastback Engine Question
« on: May 03, 2020, 02:37:01 PM »
I just purchased a 65 K Code Fastback

The vehicle was built August 1, 1964.

The matching number 289HP is included and the VIN is stamped near under the casting numbers and date..
...Not the usual front of the block.

Anyone have experience with a VIN in this location?

The vehicle's build date is as early as I've seen for a FB..

Thoughts?

1965 K Code Fastback Engine Question

Bret, the closest 289 HiPo car I can recall owning was a Dearborn built convertible with a schedule date of 15F (June 16, 1964). However the engine, which was original to the car with matching VIN stamp, had an assembly date stamping of 4G14N (July 14, 1964), almost a month later. That car's block VIN stamp was in the usual place near the front of the engine. So this car was likely built a month beyond the schedule date, possibly due to engine availability, and is about two weeks prior to the schedule date of your fastback.

It would be interesting to know which assembly plant built your fastback and if the engine assembly date is close to the scheduled build date of the car. It could be a matter of the assembly plant being initially uncertain about where to stamp the block VIN, as the HiPos were the only engines to be so identified in the 1965 model year.

165 K Code Fastback Engine Question

August 1st is an interesting date, as it was the first day of actual 1965 model year production at Dearborn Assembly. "!964 1/2" production ended the day before, July 31.

Perhaps this anomaly may have something to do with that - it is also intriguing that your VIN is 250,000. The highest 64 1/2 Mustang VIN listed in the Mustang Production Guide by Jim Smart and Jim Haskell, was 220310 built on July 31. So it appears they "jumped" to 250,000 to start actual 1965 model year production. Looks like you may have the first scheduled regular 1965 production Mustang to be built at Dearborn!

Also note the "SP PRO" stamp - could likely stand for "special production" or "special promotion" as in a showing car - does it have any other outstanding features? What is the DSO code on the tag? Car 5F09K250009, also built August 1st, is another HiPo fastback with an 89 DSO, which is Ford Transportation Services.

Bill:  I'm thinking that's possible..

However...
What would 250001-08 be?

They could be Mustangs or other Ford products.
Also...The DSO is "89" which is "transportation services"..

Likely a promotional car being so early..
And there were no 64 1/2 Fastbacks

Correct...?

See the update to my last post. Looks like it was among a group of showing cars, but there is no info on cars 250001-250008. You are correct about there being no 64 1/2 fastbacks, a perusal of the 64 1/2 VINs listed in the Mustang Production Guide shows no cars with an 09 body code.

So you have what may arguably be the first production fastback, and it's a HiPo, and it's likely a showing car. Yeow, the price probably just went up! ;)

Bill...
Is it correct to assume that 250001 to 250008 could be Mustang coupes, Fairlanes etc etc...?

Fairlane production at Dearborn ended on June 19, 1964. Dearborn also built Cougars, but that production did not begin until 1966. So I expect that these other cars were all Mustangs, but I can find no record of what specific models they may have been, or how they were equipped.

Am I missing something? Darken the mid tones in the block picture the OP provided and the last digit is a 9 and not a zero.
