The 12 vdc Cadillac brake system vacuum pump weighs 4.36 pounds on
calibrated scales.
Maximum dimensions are: 7 1/2 inches long by 5 1/2 inches high by 6 1/4
inches wide, with 3 rubber isolated mount points.  Delco part numbers:
5048967, underneath that is: 056 7 0 1 1, whatever that means.  It draws
about 25 pounds vacuum.

Hold on there. 25 pounds??? Is that psi or 25 inches of Hg?

Oops, I did it again, sorry.  That is 25 inches of mercury, as measured
by a standard Sears engine vacuum gauge.  Neither of the lab quality
gauges will give a reading because the pump will not pull down to the
millitorr range.

Btw, the pump has a fair sized electric motor driving the head; hence
the above size measurements.
