1970 Z28 VIN ON BLOCK

[StriperSS]

Isn't there a way of 'seeing' the numbers on a decked block by magnetic means. I heard this years ago and wonder if it's true or an urban myth. It seems to me that law enforcement agencies could pull up serial numbers from guns and blocks that had been filed or ground off.
The stamping disturbs the metal molecules in the areas around and under the actual stamp, so even though a layer of metal has been removed, the disturbed area still exists, and can be read with some means.
Any opinions or knowledge on this?

I would be interested in this as well. My block was decked in 1974. It is the original 327 out of my 67 Nova SS. Are there any other vins or stampings on the block?

There are a few methods to do this. Magnaflux is what I think you are talking about. There is also the acid approach. However I think you only get one shot with that one. Acid kits are available for about $125 with more stuff than you need. Might make sense to contact local law enforcement to see if the have a list of contractor that do that type of work and has the mag kit.

About 15 years ago, a guy from the V.I.B.(Vehicle Investigations Section) at the Illinois State Police we tow for out of Elgin, showed me how to use a metal shafted, cotton ball style, shoe polish applicator dipped in battery acid, and a battery charger to lift up decked numbers on a "440" cast 1968 396/375 short block I had.

The best thing about doing it this way, are that the numbers are still legible today, and according to his research, the engine is out of a Camaro delivered to Nickey Chevrolet on June 2nd,1968, my 12th Birthday!

It could have been a take out of a 427 converted car. I tried looking for the car buy Vin. but never found it.
