Brake Booster Vacuum Source
#1
Im converting over from Manual Drums to power Disc/Drum and I was wondering where on the carb the original Disc Brake cars got the vacuum?

Does anyone have a picture or diagram?   My car is a 2bbl 302.

Thanks

 Not familiar with 302's, but is there not a "vacuum tree" on the manifold behind the carb similar to the 351C?

Yes, there is a vacuum tree on 302's. Just like the one pictured.

Ok, good to know that there is a port at least for the "vacuum tree" on the 302. I thought there would be, just not sure. It's a loooongg time since I had a 302!!
If there is not a tree, where is the vacuum source for the carb coming from? If the port is plugged, then I would think any suitable nipple would work in place of the tree.

the vac source for the carb is internal. if u have a factory intake it might be plugged off... just remove and put any fitting that'll work with the p/b. if none the u may need a spacer for the carb... and thin one

Ooops, I misspoke. I meant the vacuum source for the air cleaner temp sensor...…… if the a/c is still on there!!
