1971GTO:
Guys,

1.  In an earlier thread it was discussed using a vacuum guage to dial-in the initial idle mixture settings.  Which vacuum port is used to accomplish this please?

2.  Also, locals say the vac. modulator line from the trans. goes to a lower port, but the configuration of the metal line only leads to an upper corner port.  Is the local help mis-informed?

Got my Cliff's rebuild back few months ago.  Gonna get that Edelbrock 750 off the 455HO right soon!

Manifold vacuum; not ported (timed) vacuum.
