Re: BBC how to tell steel from cast crank??
I've had a few cast cranks that rang like a bell, too. Parting line is your best bet for telling what you have. I've gotten to the point where I can look at the back flange on one and tell without having to pull the pan. This doesn't work on the late model 1-piece rear main stuff, though.
