As the title suggests...
Unless someone has been playing with inlet manifold mods. for a late Buick V6 (VN SII, VP, VR), I don't really expect that anyone will know straight away, but perhaps if you have one lying around off the car, would you mind measuring the volume?
I think that blocking the inlet ports and vacuum tap off points with masking tape, positioning the TB/inlet vertically then measuring the amount of water it takes to fill it to the brim it should work.
