How do you know if you have a 6.4 crank or a 5.7 crank?
I know about the the differences in the stroke and the 6.4 is forged and the 5.7 is cast. Parting lines are wider on the forges ones.
But do the 09 and up 5.7 have 3 bolts for the reluctor wheel like the early version?

they are all 3 bolt.

The forged vs cast is the easiest way to tell at a glance, all 6.4s (SRT and BGE) are forged, all 5.7s are cast.
