1970 Z28 VIN ON BLOCK
 

IF A BLOCK HAS BEEN DECKED BUT STILL HAS THE VIN BY THE OIL FILTER DOES THAT COUNT AS THE ORIGINAL ENGINE EVEN THOUGH THE DECK HAS BEEN CUT ?

I would say it is 50% better than no #'s at all. And the Vin # being the most important of the two. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif JMO

depending on the type of car (mopar, chevy), I would have to see how the stamp compares with the one on the trans. I think they should look similar, but for now I am not 100% sure if there are exceptions. If they are completely different then I would make sure you know why they are different before buying. I personally get nervous when the matching numbers trans is missing, as it provides no comparision.

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.

On 70's Z28 the VIN# was only stamped by the Oil Filter, engine code was on the deck.And yes that would count as original.

Actually, all Van Nuys cars appear to have been VIN stamped on the pad. Also, I have seen some Norwood cars that are pad stamped. I had one 1972 that's pad stamped and was just resold on ebay this week. I don't think there are any absolutes with these cars. JMHO, Ed

My 70, VN built, 03C, had the VIN stamped on the pad.
