Vacuum Block, Who's using them and What are the Advantages and Disadvantages??
-
Do you mean the one that is on top of the doghouse? Not sure what you mean by advantages - I have one because I had to for my vacuum brake conversion.
-
vacuum brakes?

So when I do the Vacuum brake upgrade, I should get a Vacuum block? Just seen it in "Knowledge Base Articles, Submissions, and Comments " Figured it'd be an easy way not to worry about Vacuum leaks is all...........

It's the easiest way to get a strong vacuum signal.source. I suppose you could tap into the manifold somewhere else.
It is a spot than can easily leak, you are correct. You can get a new bock and still use the powermaster, you would just have to cap it off.

Just figured with the Vacuum Block, I'd have one less thing to worry about in the long run....

The only difference between the vacuum block used with vacuum brakes and the vacuum block that is standard ont he car is the number of ports built into it.
The one for vacuum brakes has one extra port on the drivers side for the hose to the power booster on the brakes.
Originally, the Turbo Trans Am had vacuum brakes and we just got a vacuum block for that car. Then some started making blocks out of aluminum instead of plastic.
Either way, it just makes it easier to connect the booster without having to tap into something else like the pcv hose, or tapping into the intake.

here is a picture of an aluminium one on one of my cars
