My thoughts on approaching this setup:
What matters is getting the bore "true" to the outside of the casting, not the core hole which could be shifted quite badly. It's only there to save valuable material and some machining, after all.
Indicate off equally off the three jaws holding the round part, get nice and central, bore initially with an end mill so it doesn't follow the off centre hole. Face true. Bore to size. Should get in the ballpark, if I'm not missing a quirk of the casting geometry...
Look forward to seeing what you come up with!
