stroking increases displacement by moving the rod journal ( that is where the rods connect to the crank) farther away from the crank center line ( the very center of the crank). the only way you can get more stoke out of any crankshaft is by offset grinding it. its a prosess done by grinding one side of the journal, and leaving the other alone. this will cause an oval on the journal. all thats left is rounding it off. smaller rod bearings and/or shims are required.
forging is a prosses of forming metal. there is also casting. casting is where a mold is made and the material is poured into the casting. most stock engines are cast. forging is almost the same prosses except that the material is forced or pressed into the mold. think of ice cubes melted together (cast0. there is still gaps in between the ice, now compare that to a solid chunk of ice (forged). which one is stronger, the block of ice. majorly exagerated but the same theory.
if you have anymore Q's just ask. have fun
