Sonic test results
The thicker the better. Adding cubic inch displacement in this fashion is the worst way to add it on and the longevity of the block goes down along with a stiffer cylinder wall which makes more power.
Overbore as little as possible at all times.
This applies to 95% of all the people here. The other 5% (or probably less) are building dedicated and specific race engines.
Also sometimes there’s no care about the block, just the need (probably weed in science) for a big bore to aid the cylinder heads flow avoiding or minimizing shrouding issues.
