The forged cranks also have a sort of purplish iridescent hue on the counter weights
That is from oil heat treating Kellogg did on the cranks.
It looks forged and I can verify from experience all Manual Mach1's were forged cranks.
Also its a f6 casting and the 8-bolt Windsor cast cranks weren't cast until 98 f8/f9 etc.
I have torn down way too many mod motors
