1966 Vacuum System Issues

[raclark317]

Hello everyone,

I am new to the forum and relatively clueless to most things. Some 5 years ago, I started restoring a 1966 coupe with/for my son. The car we bought had been wrecked and was someone else's project car. Fortunately for me, I had two friends that were pretty awesome mechanics who rebuilt the engine (it had seized). Then I moved from the midwest to FL. While I have done a lot of reading - books and online - I know too little to finish up things and just enough to get into trouble. I will have a lot of questions.

That said, the 66 has a 289 engine with power steering and an automatic transmission. It used to have air conditioning and will eventually in the future but is lacking a compressor, pulley, etc. - pretty much everything AC related in the engine is gone. It doesn't have the thermactor emission set up (and won't).

I have put an Edelbrock manifold and an 1403 carb with electric choke on it along with an hei distributor.

So, I am having trouble figuring out what vacuum lines are needed and the photos and diagrams I find appear to have a variety of vacuum systems. Is there a good resource that will not only show me the vacuum system but also indicate what parts are for emission control, AC, distributor, automatic transmission, etc?

Thanks in advance for your help.

Welcome to Stangnet . A 66 will only have two vacuum lines ,The trany line and the distributor advance . the trany line comes from the back of the intake usually off an intake runner and goes direct to the modulator valve on the back of the automatic . The distributor vac. line will come from the bottom or side of the carb depending on what carb you have , it will be the vacuum nipple that has the least vacuum at idle but increases as the idle comes up.

Thanks, Horse sence! That is what I thought but I saw photos etc. showing a need for one with AC, and the thermactor, etc.
