How much can you bore a 460 safely, street/strip?

Hard to say. I heard of 68-70 blocks going .100 over  It's always best to sonic check to know what you can safely do. .030 over may be too much... you never can tell really.

My last was .080 and half filled with hard block, mud raced it for 6 years.

As the other guy stated, it is not uncommon to be able to bore them .080 over.  That is one of the combinations used to make 514 and 533 inch engines.  Unfortunately you never know unless you have it checked.  It would suck to put all that time/money/energy and then find out afterward that you are too thin and the block cracks or leaks.  Do yourself a favor and check it first.  I had one 71 block that with the core shift it would only safetly go .040  and that was a block I was thinking about making a 514 from.

Ditto, sonic check them. The old yellow Performance Ford book of the 70's stated any 429/460 could go .080 over, and up to .160 with checking. There's always the odd bad block, so test it first. Regards,
