Default Life of a 388 bored .060 over

How long will my 350 sbc last if it's bored .060 over? and can I drive it as a daily or certain amount of time?

Should last just as long as a block bored .030, however it should be sonic checked before having it bored to ensure there's enough material. You doing this to go as big as possible, or is that what it's going to take to clean up cylinder walls?

Just as long as you have a good cooling system and a proper tune, you shouldn't have a problem with the engine being a daily driver.

Thank you all for the replies,
I bored engine .060 because that was my option. I never asked about being sonic checked but assuming that they did. Although it was a bad idea to NOT double check.
Cooling system that I have is;
-2 row aluminum radiator
-7 blade fan/ non electric
-160 thermostat
Any recommendations on a better cooling system set up than what I have? Thanks again!
