I am looking for a good 2.0L stock crank (71mm).
It is for my race engine, so I would rather have forged than billet (like the SCAT product). Who has used a AA forged crank? Any issues? Do we know if these are brand new or reconditioned to be "new"? Anything to worry about or better options? https://aapistons.com/products/counterweigh...qxoCrTYQAvD_BwE |

So that's ballpark .175" off of one side, I guarantee you are through the heat treating.
996 cranks don't even have enough heat treating to cut them 1st under. In layman's terms the crank journal heat treat could be described as an eggshell. Very hard surface but softer underneath. |
