Identifying a GT 500 powertrain

[gpm6367]

I am looking at a GT500 and trying to identify the powertrain.

According to the former registry the last four digits of the Ford VIN are stamped on the block and trans.

Where?

Does anyone have a photo depicting the locations of the vin?

Back face of one of the heads facing the firewall. Tough to see in the car, need a mirror. On an auto trans top back of the main body just before the tailshaft housing. Faces the floorplan. Both partial vins only but more than 4 digits.

Here's a picture of the rear of the LH head that was on the engine in my '68 GT500.



It is very difficult to see.

Where is the stamp on a 4 spd?

So it's the rear passenger head that's stamped? Or block near the head?

[davez]

It's on the head not the block. Best you can do for the block is confirm a date code

On four speed it is typically stamped on the protruding pad near where the main case and tail meet. It is seen from the bottom side.

The casting number is behind a freeze out plug?

Where is the block's date code?

Near where the oil filter adapter bolts.

That would be the case on the 67. On 68 New Jersey cars they are on the left upper ear of the transmission right above where it bolts to the bellhousing

+1 .Thanks for the save. I neglected to look at the section and didn't switch gears for 68.

On some GT500s built in a certain time frame, the partial Vin may be stamped on the back of the intake manifold on the driver side. Pictured is an example along with a transmission stamping from the same car this engine and transmission came out of.

I'm having a hard time orientating myself to the location of the stamp on the block in that last photo. That is on the back of the head?

Also told that early cars did not have VIN stampings. Does anybody know when the VIN stamp began? This car was has 11/29/67on buck tag and door tag says 12/4/67. Should this vehicle have VIN stamps?

[Coralsnake]

Early cars did have VIN stampings. It started with the 1968 model year. I will show you examples if you like.

Stop listening to whomever told you that.

Casting date by oil filter is a good indication, engines could be stamped on intakes, heads or blocks. You will need to check all three.

The transmission stamping is on the left, upper ear of the case. It would not be visible when installed in the car. In the photo the engine would be in the top of the picture. The transmission input shaft is pointing towards the top in photo. The top cover is show (with bolt)

[Coralsnake]

A half dozen stampings on 1968 Shelbys with serial numbers below # 500. Now, maybe we can put that fallacy to rest.
