Garrett,
Ignore young Tom. He is still learning and hasn't figured out that he should be lurking, not posting.
There are two areas on the bore that are critically important and need the max wall thickness. These areas are between the bores (for proper cooling) and the lower outside walls (most stressed area as the piston wants to "push" through here).
Anyway, I don't have very good news for you. High power engines (600+HP) like wall thicknesses of 0.180"-0.200". Performance street engines should have 0.140"-0.160". Minimal wall thickness even for a grocery getter should be over 0.100" in the above critical areas.
If you look at my graphic (I think in pix, not charts), you'll see that your thin areas are in the worst possible place. I'd scrap that block -- you'd be doing yourself a favor in the long run.
Cheers,
Dan |
