I don't think that the stock LQ4 bottom end is going to help you. You're going to need some compression to make that work, at least 11.0 on that wide LSA, but you could tolerate even more.
You might make those numbers through an M6, but not a 4L60. If you want 460 though an A4, put a 4" crank in there to make it a 402-408.
