Super Six install on 1974 Dart
The new carburetor arrived yesterday. It looks to be well-made from the outside (not the important part, I know). It not surprisingly has slightly different vacuum ports from the one that came with the manifold. The two matching large nipples on the throttle body seem to both lead directly into the intake manifold. I assume one is the charcoal canister purge, and the other gets capped. The smaller one in the throttle body looks like it's probably the distributor vacuum advance. The small one next to the choke pulloff hose is probably to control the air cleaner inlet heat door. The one coming out the side of the bowl below the choke bracket might be for EGR control, and the large one above the bowl is clearly the bowl vent (to charcoal canister). The one between the idle mixture screws is PCV.
Speaking of the choke bracket, it looks like I might not need to replace it. It seems to have the hole oriented more or less the same as the junkyard one.
