I have run stock forged cranks for year and never a problem with them. I put a new Molnar 8 bolt crank in my new engine. Old eng was right at 600 horse power. Zero warning that anything was a miss until it exploded, tried to throw the #3 rod journal out of the block. Brian

My last one still mag-checked OK in a 600 HP build when I pulled it apart the last time, but I replaced it with a new 4340 piece for piece of mind.
