Howdy howdy.  Interesting question for an uneducated person like myself:  Does anyone have "simple" mathematics for piston compression and relation to power output?  Specifically, a piston exchange between a 1.8 and a 2.22.  Although my engine is running fine, I am thinking of rebuilding another 2.22 block in expectation of mine eventually breaking down.  I noticed that the bore and stroke for a 1.8 piston is the same as a 2.22 and wanted to know 1)Is it a possibility to swap in the 10:1 1.8 pistons for the 8.5:1 in the 2.22  and  2)What kind of increase in power am I looking at if the swap is possible.
Like I said, I am pretty uneducated when it comes to these things, so any info would be appreciated.
Mucho thanks in advance.
