Yes. There are guys going out to .090. As far as sonic checking at this dimension, I don't know the answer. I'd like to know myself. I'm going .065 with my ly6. I WILL sonic check mine when it's done. I can tell you that the gen 3/4 blocks are a far cry from previous sbc castings when it comes to quality. You just won't see the core shift issues that we used to, at least with the iron blocks.

This subject has been thoroughly beaten to death. Some simple searches should bring plenty of info.
I have sonic checked a 6.0 block at 4.080 it was at the minimum safe thickness, issue is its only one section of the bore that becomes relatively thin, not the whole bore.
4.030 max bore size for power adder
4.080 max bore size for N/A

Thanks for the input. It may seem like an old issue but things change all the time. I retired from GMPT and change is constant. Can't spend $$ on old info. I need to decide whether to go LQ9 or LSX for my new build. I'd like to go 4.100 bore and 3.750 Callies stroke for 396 inches with the LSX block or 4.065 bore with a 3.750 stroke for 389 inches with an LQ9 block. The only benifit with the LSX is future rebuilds to bigger inches. Thanks for the feedback.

I trust Fraser@AES on his recommendations on the max bore for an LQ block, but check out this thread. It has a guy going out to 4.125 bore on an LQ block. Post 29
