What vacuum lines can i pull out and plug?

The only things that come to mind that i need are
1-PCV
2-fuel regulator
3-c-4 trans trans modulator

running hydro brakes and no EGR

Then you should be good. Do you have Gt-40 p heads too? Just curious which headers you will be using if you do?

The short answer is plug the ones you don't need. I plugged all but the three you listed and used one for the brake booster.

I have GT-40 heads not the "P". From what I have gathered the best headers for the P style heads are the ones from bronco hut.

I just wanted to double check and make sure I wasnt forgetting something (I usually do)

Are you running an EGR valve?

 

[crawler73]

No EGR for me

It's best to put a plug in the lower intake, so you don't cook you throttle body.

Agreed!

By "plugged" I would suggest you tap for NPT pipe plugs. I used a combination of 1/8" and 1/4" plugs. Don't rely on those rubber vacuum caps.

I actually have a lower intake off a newer explorer so I don't have that hole for the EGR so that makes things easy for me.

And yes by plug I meant actually NPT pipe plugs.
