need some help with vacuum lines

[guitarfreak235]

hello all I am finishing my engine swap tonight. just a couple things and im done.

i have a question regarding vacuum lines. The engine is a 350 from a 75 1 ton. I think the only vacuum lines i NEED are vacuum advance,pcv,brake booster. Is there any thing im forgetting?? How many of the vacuum lines on the carb are plugged?? thanks for the help

There's also the little vacuum line that goes to the HVAC control.

It shouldn't really matter what year and what vehicle it came out of. I'd try to hook up everything that your truck has now and put it back the way it was on the old motor.
