Here’s a block you don’t see everyday

What is the thinnest wall you want to run ?

I don't like less than .160 and if you are going to beat on it, like 2 HP/CID and/or over 8000 RPM I like .190 at the minimum.

I didn't sonic this new X block I have, but I should have. I will do the R when I get it.
