Hey, I am getting close to being ready to try starting a '79 633CSi after replacing the head and resealing the bottom end. It was desmogged by Miller Norburn when it was new and has a bunch of Alpina parts installed by them as well. It has vintage Supersprint headers and a full Primaflow exhaust. No thermal reactors or smog pump.
What I am unsure of is the routing of the 2 vacuum lines from the distributor, all of the diagrams show only one. All of the diagrams though reference the points type distributor and this has electronic ignition so that might be why? Both go to the throttle body I think but not sure which ports.
