NOTE: This is a NEW, Crankshaft.  No GM PN with this crankshaft to determine specific application (90~92 or 93~95) on crate.  Crank is stamped & tagged T13-107.  Crankshafts are visually the same for both generations.  The only difference between known GM part numbers is the bob weight used to perform factory balancing.  Bob weight for piston/pin/rod assembly is different between 90~95 375Hp and 93~95 405Hp engines.  

This crankshaft should be balanced with corresponding piston/pin/rod weight before installation.
