Stroking and Boring a motor are 2 different ways to increase the displacement of an engine. Stroking works with the crank/rods to allow the piston to travel a further distance as the person above me stated. Boring makes the actual diameter of the cylinder larger to accommodate wider pistons.
For max block strength on a boosted application it's best to leave as much meat in the cylinder walls as possible. Drawback of stroking is the piston now moves much faster up and down and decreases rev limit.
Its best you stayed 4L if your end goal was high boost and 9K RPM
