New guy here with a question.
First off I'm going to get pictures up asap! but I'm trying to get my truck running. just dropped in a late 70s model 305 and I'm trying to figure out what screws into the intake manifold on the number 8 runner. it's roughly a half inch hole. any ideas?

Re: New guy here with a question.
Depends on the intake. More than likely a vacuum port for emissions or break booster.

Either a vacuum fitting for power brake booster or a plug. LockDoc

Re: New guy here with a question.
I'm guessing just a plug then cause I see where the booster hooks up. the one at the junk yard was missing it as well.

Re: New guy here with a question.
From the factory, that hole is the port where you hook up a vacuum line to the automatic transmission modulator. The brake booster vacuum line usually came out of the rear of the carb.

Re: New guy here with a question.
Yup. You can even see the capped booster vacuum line over where there is no booster. And it comes from the back of the carb. It's a lot of flow when it's in use (say, brakes being pumped, or the booster leaks), and you really don't want it on just one runner.

Re: New guy here with a question.
yep thats where you can add on auto trans vacuum or change your brake booster from the carb to there. Depends on clearance.

Re: New guy here with a question.
thanks guys! reckon I'll be heading back to the junk yard to see if I can find that fitting since I do have a 350 trans. it's not the prettiest right now but my first priority is getting it safe and drivable and then taking care of aesthetics.

Re: New guy here with a question.
Thanks for pointing that out! it definitely makes sense. I'll keep my eye out for it when I'm scouting for the vacuum fitting
