In need of an education..340 vs 360.

The 360 easily bores .070 over to make a 416. I've done two, and two 408s as well.

That makes it as cool as a 340 stroked to a 416!

But .070 over...Ouch. No problems with them at all? Do you race them? If so did you fill the blocks? I assume that sonic checking beforehand would be an absolute must. Personally I would be more comfortable with a thicker bore than a few extra cubes but that's just me. :)
