Does it have 8 bolts for the flywheel instead of 6?

could be Gen4…could be Gen5…no sure what this is just yet. 8 bolt flange will tell the tale of it being an LSA. I’m suspecting a Gen5 crank myself.

It`s an 8 bolt flange. Was told it came from a 2014 CTS-V, (which would be gen v?) I only ask my question of "what do I have" because when I look up gm lsa crank, I get part # 12641691. Instead of whats on my crank 12644567....

If it is a 2014 CTS-V engine, it IS a Gen IV LSA. It was made through the 2015 model year
