Title: Acid etching engine block stamping numbers
Post by: Lucky65! on February 08, 2024, 04:53:47 AM

Has anyone had any luck acid etching a block to raise missing/ ground off stamping numbers? What acid is used for cast iron?

We had two links in the engine section but they don't seem to be working right now. I am checking on them.

I have tried it before but did not have any luck.

I dont think I have ever seen anyone have luck doing this.

Is $350 too much to gamble on being able to find a serial number, and then finding it to be what you are hoping for?

Depends of the depth of the decking. There's a quote in that link from someone that was successful.
