What stamp do you mean? Date?

Cheers

They were supposed to be VIN stamped per federal law. I believe the law went into effect January 1, 1964. At the time all 4 speed transmissions were to be VIN stamped due to theft and pawn shops / junk yards / speed shops acting as fences.

They didn't have a Vin stamping but they have casting numbers and date of assembly stamped onto one of the flanges.

My understanding is that San Jose K codes with 4 speeds (which became 66 Shelby GT350s), almost always had the Ford vin stamped on a boss on the bottom side of the transmission.

The k-code Mustangs with the close ratio Toploaders were stamped with VIN.  AFAIK, the k-code GT350's with the T10's were not.  It has been discussed before as well and I have never seen a GT350 T10 with a VIN stamp.  Not sure why.  I am not sure on the C4 automatics, but I don't think they were VIN stamped either.  The 66 HiPo C4 I have is not VIN stamped.

I agree with Cory on the 66/ 65 GT350 T10's ,no VIN stamped. The 66 G350 C4 wasn't stamped ether. Best you can hope for is date codes on components to determine if appropriate for car.

Hi Bob,

Any guesses why the GT350 tranny's were not VIN stamped?

Take care

Sorry,that I can't offer any more insight other then the obvious one that they thought the engines being vin stamped in this particular instance was enough at the time. I suppose that will have to do until more compelling information suggests otherwise.

Stephen,where exactly(what location) have you seen a vin stamp on a 65/66 Shelby aluminum case transmission? For the life of me I am at a loss to understand what boss on the bottom of the T10 transmission it would be stamped at that you are referring to .  A toploader yes that is easy. A T10 I would need help understanding where that boss may be.

Pretty sure we discussed this in the past on crashed forum 1.0. I'm not aware of evidence that any of the 65-66 GT350 T-10M versions (aluminum/aluminum, aluminum/cast iron, cast iron/cast iron) were VIN stamped.

And the T10M1's did not come with a tag, but will have an assembly date that should precede the cars San Jose assembly date.  The HiPo C4's did come with a tag and date code, also preceding the San Jose assembly date.

and not all the Aluminium T10 on 1965 GT350 had an assembly date code ...
