ok to use same vacuum line for vacuum advance and tranny vacuum modulator?
 

I had to block off the vacuum port on my performer rmp air gap intake because it was in the road of my carb. So would it be ok to just use a vacuum tee and tap into my vacuum advance line?

No!! That same vaccum being used to advance your timing will be used to shift your tranny. Not good. Tee off fron some where else.

I have one other vacuum port plugged off on the carb. It is a bigger port than the one i am using. Does it matter. Which one should i use for the tranny?

You need manifold vacuum for the tranny, does the port you have plugged pull vacuum at idle? If so ,use it. Use the port that pulls vacuum when you open the trottle for the advance. :D

72 chevy said it better than i did. Let us know how it turns out.
