Observations about wear from compression ratio and stroke:
If static compression were an issue, diesel engines wouldnt last very long.
I don't know that the marginal increase in stroke itself [ie piston travel]is a significant factor in ring wear. What I have observed though is that longer stroke engines, particularly with shorter or less than optimim rod length:stroke ratio seem to have much worse bore wear, probably from the side load. The bores almost always seem to be out of round
May be less of an issue with lower RPM/load and higher nickel blocks.
