Yea, I had my builder key it.

 

seems as though the crank snout is fine. like they say, the hub is a much softer metal than the crank. Going to lightly sand the crank and install a new hub.
I also believe the opti is now junk. Going to sheel out some more cash for a MSD and use the longer screws and loctite.
Also going to remove the timing chain as I think some shavings might have gotten up in there. Then change the oil.
Im guessing it's still not safe to put Synthetic in?
thanks

 

don't use an MSD opti, get an OEM Delco/Delphi unit

 

so the msd isint any better even if you use the longer screws and locktite
