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.
