Your always hereing ppl talk about there Engine builds "I've got Endyne (SP?) pistons", or "I just got me Eagle rods" But what about Crankshafts? I was just thinking about this and I can't remember anyone saying anything about this. Do you just buy OEM Shafts according to block type? Or is it more application based? Or do you buy aftermarket? Please shead some light on the mistery of the shaft... umm yeah , that didn't sound right .
