Bad Bob Posted July 13, 2016 Share Posted July 13, 2016 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. Quote Link to comment Share on other sites More sharing options...

Tony D Posted January 3, 2017 Share Posted January 3, 2017 "Forging Numbers"...none of them are cast, they are all forged and the numbers are die numbers used in the forging process... Quote Link to comment Share on other sites More sharing options...
