Decode Vin Help- Y engine code?

F10YD803091 is the door tag warranty code. I can't make sense of the Y for engine type HELP!!

F10 the Series: F100
Y: wtf?
D: Dallas - yes likely as it's a Texas truck
803091: consecutive unit number
115 Wheel base, she's a shortie
B: color code Turquoise - yes
F100 - yup
C81- conventional cab in green vinyl - yup
C: Manual 3 light duty
08: axle code 3.5-3.3M
5000 GVW
172 hp @ 4000rpm
District code #62: Houston

My misunderstanding stems from the Y code. I'm the 3rd owner and I knew the 2nd owner, neither of us swapped the engine. according to Decode Your '65-'66 Ford Truck VIN Tag - FORDification.info - The '61-'66 Ford Pickup Resource the "Y" is a 1966 8cyl 352 cid 2v 208hp@ 4400 rpm. but the tag says 4kRMP with 172 HP, which seems low for a V8.

So, is the Y correct? Did it start live as a V8? what else can I check? I'll look at the frame code tomorrow in case the door was replaced some time.

It's a 1966.

The dead bang give-away is the Y VIN engine code and the Numerical Sequence of Assembly (803091 - last 6 digits of the VIN) that decodes to a 1966 assembled January 1966 (edited into post #2).

Correct V8 for 1965/67 F100/350: 352 2V

4th digit of the VIN is the engine code. D = 1965 352 2V // Y = 1966/67 352 2V

TIBI,
I know you mentioned you've been working on this truck for a few years now, but have you ever compared the VIN stamped on the frame to the VIN on the door tag? Maybe you should check to ensure they are the same....sometimes doors get changed out but the owner does not exchange the VIN door tag. You could have a '66 door on a '65 truck............ it's worth checking if you haven't already......although it may not make much difference to you if you aren't doing a concourse-correct rebuild.

I know it happens because I have had one truck without any door tag and another with two different VINs , frame vs. door numbers.

F10JD638359 is what is on the frame. It's funny I've never taken notice of the numbers anywhere on the vehicle. The "6" of the warranty # is difficult to read. Engine says C5AE-6015-F then a few other digits... "?A14" I dont know what the first digit might be. On the transmission there is 5A12 stamped separately then two lines: G5AR with 7009 below it. The rear diff has 5A9 5A11 DIFF and 26 stamped in various places. I have photos of all those if I'm not being clear.

Your frame VIN is stating it is a 1965 and I believe the J engine code is a 240 straight six but could be the 300 Big Six. D would be a 352 V8

It has to be a 6, because if it was a 5, it would be a 1964.

Engine says C5AE-6015-F then a few other digits.

"?A14" I dont know what the first digit might be. On the transmission there is 5A12 stamped separately then two lines: C5AR with 7009 below it.

F10 = F100 2WD // J = 240 1V I-6 // D = Dallas TX Assembly Plant // 638359 = 1965, assembled January 1965.

?A14 = January (A) 14, 196?

5A12 = January 12, 1965 (5).

5A9 = January 9, 1965.

Great help NumberD & RangerMM! Seems like there is conclusive evidence that the door was replaced at some point, and that the engine, trans & rear dif are all original. From what I understand, the "A" code on the engine means 240 but it is possible that it could be a 300. However, not likely. Furthermore, the surest way to check is to measure the piston travel. I think I'll do that while my gaskets are in the mail, and the manifolds await reassembly. If I come across anyone that re-manufactures door tags I might get one made.

Marti Auto Works can apparently reproduce your door tag given all the info you have. I am in Canada so I cannot help you with him.

Your photo depicts a two reservoir unit. This update is a highly encouraged change as it makes for a much safer truck. The dual pot master cylinder units came in '67 and later model trucks.

If I get a reproduction made by Marti Auto Works, is there any way to confirm the trans, axle and D.S.O number?

The trans is a 65 3 speed manual so that would be an "A" code
The Axle Code and D.S.O # I'm not sure. All I know is it's a 9" ford rear differential.
