I just did a disc brake conversion on my 72 Chevelle and everything went great until the end. Where the heck to I plug the vacume line from the booster up to? There is no place on the intake, and I cant find a spot on the carb either. Edelbrock intake, Holly carb. The motor is a 350. Will there be enough vacume to tap into the transmission vacume line? I didnt think that would be a good idea, but wanted to get some input first.

My holley has a large vac line in the rear below the rear float bowl. If I remember I think I had to put a T on the line for my wifes car because it was also being used for something else. Maybe this will help.

I used the vac. line where my pvc valve was hooked to on my holley its a 3/8 line like the booster hose. just t'd off like patrick was saying or you can t off your intake also. the tranny line should be hooked somewhere on the intake. You can bye these t's at any napa store.
