Ok, I've always heard that the K-Case autos were heavier than the "standard" variety. Everyone seems to agree that the bell housing is thicker, and some claim that other parts of the case are also heavier. However, I have cut the bell housings off of a "standard" and a "K" case now and I can find no difference. They both mic just below 0.150, bolt bosses are the same, etc. In short, I can find no difference at all... Am I missing something? Does anyone know *specifically* what the differences are?
