Yes it was an O.E.M. steele crank.It had over 900+ passes on it with one freshening up after about 325 or so.I bracket race alot,sometimes twice a week.The engine had the usual great oil pressure before I was making the pass it let go on.Right before It was going to make the shift to 2nd gear it broke.After tearing the engine down,the crank was broke in 3 pieces.But the main webbing on the thrust main was busted from the crank bearing all the way up to the cam bearing.So I,m not sure which let go first the block or the crank.
