Actually, No, it only goes down further...... ;-)
By changing the geometry (rod length and piston pin height), the piston can
stop higher, lower, or at exactly the same height in a stroker motor as a
stock motor, while overall travelling the extra distance of the stroker
crank. This can be used to increase/decrease compression ratios and
squish/quench clearance (distance between top of the piston and the head). I
would try to bring the piston to block level or slightly higher to maximize
the squish/quench, as long as it doesn't push the compression ratio too
high.
