Great pics for what you see under the plenum. Just my $.02 on the vacuum pump: My Z did not have one and ran pretty good. I was told by someone (Graham B) that the Yanks made them put one on for some edge of the envelope cases. I drove my Z pretty hard both on the street and racing of all different kinds and to my knowledge did not suffer from vacuum loss. However, I know many of the Z owners will say they need the pump. Just saying that mine did not. And that old Z of mine did run pretty good for what it had done to it.
