Looked at Some Motors Today

just had my 71 340 block sonic checked when it was already .030 over, my machinist told me there was tons of meat in the bores and .060 over would be fine, though louder (more engine noise, not exhaust concerned) due to the more you bore the more loose they tend to be, and possibly hotter, but im not worried about it, i wouldnt be too concerned with .060 as long as the bores and honing jobs look good
