Compression ratio?

If I use lower compession pistons, but keep the stock length rods and bore, will the displacement change?

Or does displacement only change if I change the length of the rods or bore the cylinders?

Thanks

Lower compression pistons do not change displacement nor does the length of the connecting rod.
The bore size affects displacement as does the crankshaft stroke.
The connecting rods just "connect" the pistons to the crank.
