Nearing the end of the new 400 stock install and have a few questions/
Where does the distributor vacuum advance get connected to? I'm told a ported vacuum source (by MSD), but which connection on the stock 4GC carb is ported?
There is one port on the rear of the base plate, and one port on the protruding side tube that the transmission modulator is also connected to. This tube is also connected to the base plate, and has the flared port fitting for the tranny modulator line, and an additional port. Are not base plate ports full manifold vacuum? I do not see these connections in the assembly manual.
