>>>Bigger displacement with the same-size bores comes from increasing the 
stroke of the pistons in the bores (hence the name stroker motor.)  This can 
be done in a variety of ways--moving the wristpin upwards on the piston and 
using longer connecting rods, or using longer rods with smaller bearing sizes 
and modifying the crank, or creating a crank with bigger throws--or a 
combination of the three...
