Alright, so I bought an EVTM, and I am beginning to decide what wiring and vacuum stuff I can eliminate at the carb swap. The wiring seems to be straightforward, but I have some questions about the EGR, and also what do use for a vacuum source for the vacuum advance.
Currently, the EGR valve source and vac. advance vacuum sources are "looped" into the same vacuum "circuit", if you will. The problem is, there are a bunch of temperature sensors involved in this loop that open and close smaller loops in the circuit depending on engine temperature. I want to elminate these temp sensors, and just have a single vacuum source for the vacuum advance, as well as for the EGR valve.
For the EGR valve, can I just hook that to the main vac. port at the back of the intake? Or do I need to go somewhere where the vacuum is timed, etc? For the vac. advance, is that timed vacuum, or should I just use the rear vacuum port? The carburetor I have (Edelbrock 1406) has a timed and regular vacuum ports on the front. Which carb port (if any) should I use for the vac. advance?
