Nope, .060 is normal max with sonic test.
I've seen a .080 overbore on a pure racing application, didn't last long.

The 4.100 were popular a few years back. Most of the first true LS1 strokers were resleeved aluminum blocks that netted 422CI with a 4" stroke. Seems like they are a thing of the past now. The Iron 408 and LS2 402's have taken over.
