Protect-O-Plate Question for '70 LT1

[47Hammer]

My Protect-O-Plate reads V0323CTB and the block pad stamp is V0327CTB. Is that normal to be off a few days? Any thoughts?

47 Hammer. First off, you'll want to carefully clean the paint off of your stamp pad to confirm that it is an original stamp (broaching and comparing partial VIN to tranny partial VIN - as they are stamped at the same time, if applicable). These are supposed to be left unpainted anyway. A solvent such as paint thinner or brake fluid carefully applied should do the trick - avoid wire brushes as it may deface the stamping pad area. Errors between paperwork (POPs, build sheets, etc) and the actual stampings on the car are more common than you may think. So, it is not out of the realm of possiblity. The smart guys will chime in here, but the stamp pad is stamped for application (not partial VIN) at the factory where the engine is assembled at the time of assembly. The POP would be stamped at the car assembly factory - so if the stamp pad was misread the error could be introduced at the time the POP was made. Post a picture after you clean your stamp pad and post a picture of your tranny partial VIN if you have one.

sure looks like a fresh pouring of paint on there for some reason. clean it up and see what you got.

Sam, Guess what? Non original Trans, T 10(bummer) but most everything else on the car is there. The motor was rebuilt a couple of years ago and decked so the vin# is gone. I just had the engine compartment detailed and had a chance to take that picture without the alternator on it. I have been under the car looking for the stamping around the oil filter but can't find anything. Maybe i'm looking in the wrong place, Anybody have a picture of the vin stamping down by the oil filter on a '70 Z28? Thanks.

[47Hammer]

I did that.

If your engine was decked, then you wouldn't have your original application stamping anyway (in most cases). When the engine was restamped (if that is what was done) maybe that person mis-stamped the application code. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

My car was built @ Van Nuys, Are the #'s in the same spot? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

van nuys car should have the vin stamp on the deck as this pic shows...

Be careful Bart it's probably a restamped block. A previous seller claiming the block was decked should of been when the red flag when up.

To answer your questions specifically, no the 2 numbers should be identical. The number on Portect-O-Plate is actually taken from the engine stamp.

[47Hammer]

Hylton,
Thank You, If the numbers are off by one didget could that be a legit mistake? (At the factory)What are the odds that someone found a block that was 4 days later. I don't belive it's a restamp, why would they restamp the wrong #'s when the Protect-0-Plate has been with the car the whole time. 323 on POP VS.327 on the block.

[Hylton]

I would not say a number could be off by one. More likely that there would be a typo. The guy who stamped the Protect-O-Plate might mistake the number "8" for the number"0". The same applies to the tranny stamp and the rear-end stamp which should also be on your Protect-O-Plate.

[SMGCO]

The guy that restamped the replacement block should of been wearing his reading glasses.
