There seem to be several options before me.
I haven't made up my mind what to do.
So, yes, I'm interested in all possibilities.
What should one expect , difference wise, when building a motor with varying compression ratios?
I have leads on pistons with 8.5:1, 10:1, 10.5:1 and 12:1.
I don't understand fully. ( little help here

)
