Cylinder wall thickness

Great link! I have read this before but still a good read. I am considering having the metal hardness checked as well.

I kinda figured you did, since you're a big block guy. But, that is great info. So many myths out there. I used to get newer 440's and 400's for nothing! We cut a couple apart along time ago in the machine/ speed shop I worked at and new what was up! Of course we were welding and offset grinding cranks too! Anyhoo, keep us posted young blood!
