1973 351 H code vacuum routing

[Mikes73]

Hello everyone, we are currently doing a complete restoration on a 73 sportsroof, 351C 2V H code, FMX trans, 2.75 rear. The car now has a 70 351C 2V engine in it. The distributer has 2 vacuum connections on it, does one hook up to ported and the other full vacuum? The car has a 4 line vacuum tree on the firewall that currently has no lines hooked up to it. Does anyone have any pictures or a diagram that I can use as a reference to get all this straightened out thank you all very much, this is a great site with a bunch of knowledge in here!

The fitting on the firewall is the source for the transmission vacuum line, EGR (carb base plate unit) and the interior vacuum that controls the heater / AC module.

An engine vacuum source hose plugs into one of the ports and that feeds the rest.
