Does anyone have handy the bore, stroke and rod length for the M106 block?

Thanks

Maybe an easier question -- is stroke and rod length the same as another M30, i.e. same rods and crank as 3.3 or 3.5? I do still want to know the bore if anyone has the spec.

EDIT: Note to self, don't ask tech questions before caffiene has kicked in...

OK, full circle.

Second note to self -- remember that once caffiene kicks in, you will remember how to Google.

Sounds exactly like an m30b34 green motor, except with a the dirty motor cam. Interesting combo.
