Which vacuum ports on my Quadrajet?
How do I find out what ports to use for my vacuum advance, transmission modulator(It is connected correctly I hope) and the vacuum ports on the dual snorkel air cleaner on my 7041251 carb I had built by Sparky. There is also a brass nipple on the top rear of my performer for direct manifold vacuum. In the pictures I have capped the three unused tubes on the carb and the one on the intake so you can see them better. This is on my 68 442
Any input would be greatly appreciated.
Thanks

This should help with some of you questions:

Distributor vacuum advance typically connects to the capped port above the idle mixture screw on the driver side of the carb.
Auto-thermic valve on the air cleaner should connect to the manifold vacuum port on the rear of the intake.

Frankly, I was embarrassed to ask Sparky cause it has taken me so long to get my 442 running again. I have sent him a note and I'll see what he tells me. Thanks to you guys, Eric and Kenneth for your input.
