Did GM ever stamp vin information onto SBC engines like passenger cars ? I have only ever seen plant and date stamp.

57taskforce · 08-14-2021, 07:58 PM

No not on 67-72 trucks.

**68bowtie** · 08-14-2021, 09:32 PM

No argument here

**MJN** · 08-15-2021, 12:05 PM

Truck engines got the VIN stamping starting in '73.

I guy just sold a C10 on BAT for $35K. Is insisting the engines where stamped with vin #.

**Steeveedee** · 08-15-2021, 06:18 PM

One could retroactively stamp a VIN. I'd think that it would be pretty obvious, though. It's not easy duplicating the factory stamp.

May have been dependent on the model.
In 1963 the Corvette's had the vin on the motor.

This is true, Cars had them long before the trucks did. Again no factory stamps on 67-72 trucks.

Corvette's began getting VIN stamping part way through 1960 with other applications soon to follow- per The Lime Book.

My 66 ss chevelle has the vin on the pad on the original motor my car was even registered with the engine # I had to supply a picture of the vin on the post to get it registered with the complete vin.

Best you can do with the 67 -72 trucks is the date code ,engine would have been made a short time before body .

On trucks GM knew engines would be changed out regularly as they tended to be abused.

Thanks guy I just tried to educate the fella. On BAT it’s normal to call out misinformation.

If that truck's engine has a VIN stamp that proves it's not original

**YellowK5** · 08-18-2021, 02:48 PM

My 72 K5 had no Vin on the block. But the 77 350 block I am using now does

54blackhornet · 08-18-2021, 03:34 PM

There you go ! Go doesn’t even know what engine is in the truck ? 35K is crazy to.

Yeah right, that's a good one. Reminds me of the other day, where I learned the 1972 rearview mirror is on the headboard and the 71 mirror on the windshield

He drove a "Super"

At least on a BBC, the rear LH side has a part number & date stamp, and on the front RH side something like.......T0426TKB. T stands for Tonawanda plant, and 0426 is for April 26th. The TKB suffix code means 71-72 truck L47, with a 400 transmission.

The intake is stamped and dated too, heads are stamped under the valve covers. With some rational and a little search it gives a guy a solid idea whether or not the block is original, though you need to know the build date as Customcamper said to know for 99%ish sure.

In other terms.........the blocks in our old trucks are "numbers matching", it just doesn't include a VIN.

54blackhornet · 08-18-2021, 06:48 PM

The guy insisted his had a vin # stamped where we know the plant and date are .
