Anyone ever run across the aprtial VIN stamped over the top of the build date and suffix?

It's on a '73 Type LT

Personally I have not. Can you post a pic of it?

I will , just didn't get the chance today

HERE it is:

The car codes as a 73 type LT wiht 4 bbl...so the "CKD" lines up..build date on the car is 07C so a build date of "V0712" would work also. the "3055" stamped on top is the same as he last 4 digits of the VIN...there is a faint "9" preceeding the "3055" which is also consistant with the VIN

looks correct

Looks fine to me also!

so have you guys found a car with a double stamp like this? I know they could get sloppy at the plants but....

Also, I thought after (well, during) '69 the partial VIN was relocated to the oil filter boss becasue it was too difficult to stamp the pad on teh line witht eh alternator hanging over it...

My 73's is up on that boss and NOT by the bell flange, so I don't agree with that.

I have owned several 71-73's, and all have had the partial VIN on the pad along with the suffix code.

that's very interesting indeed...I know it is well documented amongst '69s that the partial VIN stamping was relocated to the side of the oil filter boss due to difficulty on the line stamping around the alternator (relocated for '69 into the spot that it would sit for years)...I had assumed that since all Camaro plants changed this procedure in '69 that it would have stayed that way going forward (especially since the alternator remains located over the pad)...I've got a few '70 blocks here, I'll check them also

thanks for the input guys

While I have never seen this, the chances are excellent its correct. Anyone faking the codes would not want to do this.

fwiw-They had a few seconds to stamp this con vin on the engine and the trans. I doubt the person stamping it cared a rats rear end if he stamped it on top of another code, all he knew is he had to stamp maybe a 800 engine that shift.


The beginning of the engine dress line was a sea of racks full of engines and transmissions; small-block V-8's from Flint V-8 Engine and Tonawanda, big-block V-8's from Tonawanda, and L-6 engines from Flint Motor, plus manual transmissions from Saginaw and Muncie and automatics from Toledo, Cleveland, Warren, and Willow Run.

In the engine schedule area, the operator grabbed the next Broadcast Copy from the printer, verified the sequence number, noted the engine code required for that car, and moved an air-powered overhead hoist on traveling bridge rails over the correct engine rack. The specified engine was hoisted out of the rack and transferred to the next hook on the overhead engine dress line conveyor, where the throwout bearing (on manuals) was greased and installed, along with the clutch fork boot. Another operator on the other side of the line repeated the process with the specified transmission, which was then installed and bolted to the engine; on automatics, an air tool was used to rotate the flexplate, and the converter bolts were driven, followed by the lower cover.

The VIN derivative numbers were stamped in the next operation on both the engine pad and the transmission, using a gang-stamp holder and a hammer. From here on, all the detail dress items were added (plug wires, coil, engine harness, battery cables, carburetor, pulleys, alternator, starter, fan and clutch, A/C compressor, power steering pump, transmission cooler lines and fill tube, A.I.R. pump, diverter valve and air manifolds, drive belts, dipstick and tube, oil filter, engine and transmission mounts, PCV plumbing, vacuum fittings, fuel pump and fuel line, radiator hoses, and (if applicable) the transmission-mounted 4-speed manual shifter and linkage was installed and adjusted (3-speed manual floor shifters were mounted on the cross-member and adjusted later on the Chassis line). Engine oil and transmission lube were added, and the completed engine/transmission assembly was conveyed to the Chassis Line for installation in the subframe. The engine line inspector wrote the engine, transmission, and carburetor codes on the Broadcast Copy and put the sheet in a box for pickup by a Scheduling clerk (needed to create the P-O-P at the end of the Final Line).

Flowjoe, How you doing?

From your photo, it appears that the stamp was not perfectly flat when the person struck it to the block as there is some residual markings on the left. This was not uncommon and is also found on engines up through 77 from what I've seen.

One of our 74's nad 77' Z also had this when I tore down the engine. I was the original owner so I know this never was messed with. Don't know how much farther up the line it went though.

I'm doing well how 'bout yourself?

I've seen irregular stampings such as you describe or what we see here. Waht I've not run across is a flat out over the top of stamping like this. As I metioned I thoguht that the proceedure was changed starting in 1969 to stamp teh VIN by the oil filter. I'm surprised to see it come back on top...like I said...I've got two '70 blocks here I'll check those out. Can I assume by your comments that the '74 and the '77 had partial VINs on the pad?

My 70 SS 350 only has the engine suffix stamped on the pad. The vin # was stamped down by the oil filter.

My 73 has vin # and engine suffix stamped on the pad.

Looks like someone got a little happy with the gang stamper on your pad. Maybe had a few at lunch that day.:confused:

Hope this helps...

As I posted above, I have only owned 71-73's that have had the VIN on the pad. Based on what I have read here and other places, it appears as if the partial VIN near the Oil Filter was done mostly in 1970.

Think you are correct on 70 being the only year for seperate stampings on 2nd gens.

my 73z has the numbers in line but are different sizes. that might be the norm but i thought i'd throw my 2 cents in=by different sizes i mean that the last 5numbers are bigger:bowtie:
