1970 Z28 VIN ON BLOCK

[67 Nova Boy]

Not an amateur my friend....I have 31 years of forging with heat. I make high end fasteners for the space shuttle/boeing and work with all temps to very close tolences. Have I done a block? No!! Will I try...Will think this thru for sure. Oh yea....I made SPS rod bolts that we all used back in the day. Ya know what's in my motor. Thanks for the info, well taken.

I was not implying you were an amateur at anything other than raising stamped numbers off of a cast iron block.

I'm just giving some advice on the subject since I do have some experience with the process and one mistake using the destructive heat process and the numbers you were trying to raise will be gone forever.

Anyone attempting to raise a serial number would be much wiser to use a non-destructive method if they have not done it many times before, or at least practice on some non-valuable blocks beforehand.

Here is some background info and a company that sells the appropriate crime scene kit.

Thanks for the info. Has anybody tried this kit or one like it?

[67 Nova Boy]

Yes....I was NOT trying to be rude in any way!! I was very thankful for the advise you have given my friend!!
I'm a very laid back person and easy to get along with. I'm new here and do not want to get anyone mad at me!!

No problem.

Just looking out for my fellow car guys (you're included).

BTW, as a machinist do you have access to a magnaflux machine? There is a non-destructive method to see the numbers with a magnafluxer.

[67 Nova Boy]

I think we do?? But there would be no way for me to bring it in to the plant. We have this "NO" government jobs allowed! The managers ruined that one for us. But will look into the acid method or the kits you have listed.

It would be great to see the numbers that have been gone for 35 years.

My company I work for...We use all types of ACID to bring out heat patterns of bolts and was thinking that it might work on bringing out the VINS.on my block.
