Troubles taking a 360 .060?

I am with Rusty here, I have a 1975 360 block out to .070 and the thinnest cylinder wall will take a .100 over bore and still have enough meat left in the bore. The machinist who checked my block said he has seen 340 and 360 blocks at .030 over that were at there max bore. But he did say at the time he did a early 340 block out to a 4.125 bore that could have gone bigger. Sonic test it's the only way to know.
