Anyone know how much a stock 5.0 flywheel weighs, or do you have one laying around that you could throw on a scale? I'm trying to compare stock vs. steel vs. aluminum. I thought billet steel was lighter then cast iron, but I'm not so sure now. If the steel flywheel is gonna be heavier then what I have now, then I'm going aluminum for sure... I think steel is around 25lb, iron is 21lb or so, and alum is 13?
