Has anyone thought about lightening the stock crank pulley? I am wondering what you guys think about taking some of the mass off from a stock crack pulley, would this IYO make a difference. Maybe my drilling some holes in it to lighten it, would this weaken it too badly? Just wonderin' what yall thought.

I would be careful about drilling holes in the pulley or lightening it without some precise machining equipment. If the pulley is not balanced, it could wobble and cause engine damage or belt breakage.
