362.5

Generally not considered safe to go .060 over without sonic testing. Walls are often too thin with that large of an over bore. Can lead to cracks which essentially makes the block a boat anchor.

Re: Motor bore

As far as I've seen/heard, .040 is about as big as you can safely bore a 350. Key word being safely....sure you can go bigger but as GeneralDisorder mentioned the walls get pretty thin.
