How much PUNCH

[Identity Crisis]

I am starting to pick up the parts for the block build up on the 3.1LV6.

Does anyone have information on the MAX safe amount that I can overbore the cylinders?

There used to be a page that gave a graphic representation on the danger amounts with bores, anyone remember this?

I am thinking of going as much as 40thou. Comments Suggestions opinions, please.

.060 is max but the less the better. .040 is fine.

That is what I was thinking .40
