I've never heard it referred as "wet mag".......but I believe that's what you or Mike mean.
And yes , I have the option of using traditional mag or FPI.

wet mag is FPI when translated from hillbilly. Use the FPI on crankshaft.
If I didn't know anything about this crank and came into my shop,my first guess is it's cracked and would be surprised if it isn't.
I can't tell in picture but has the radius been ground less than original. Been reground and radius reduced? Normally BRC or any aftermarket crank would have 1/8 (.125'') radius at the least,can't tell about crank in picture,but rod bearing doesn't look like it would clear a .125'' radius,looks like it doesn't have the chamfer or narrowed to clear, if radius has been reduced that weakens crank.
