Hi Guys Can anyone tell me the engine origin of the codes cast on L6 crankshafts. Is there a list I could look up? I bought a lot of stuff from Electromotive in the late 80' early 90' when they were clearing out their racing Z program. I have 15 cranks of various type including P30 and E31, even some with no cast marks.
