.060 Over 340....Your Thoughts?

All you "sonic check it" guys don't have an answer for this? I'm curious myself, why sonic check it if you don't know what's acceptable?
For a stock build, if you have .100" on the major thrust, and .070" on the minor thrust, it should be fine. A motor making a lot of power should be more like .180" major and .150" minor. Good luck on that with a stock block.
