Maybe we could backward engineer it then,
For example, my heritage is with V8 engines, to set a ring gap, we use a base formula of .0050 per inch of bore (you would use .0045 for a tight ring and .055 for a loose high revving thing) as a rough guide so for a 4.0350 inch bore you would have;
.005 x 4.035 = .020 or 20thou ring gap.
Piston to bore clearance is calculated similarly and so on and so on...

Is any of this making sense or shall I just start asking questions one by one as need be.
