Id put it on your intake. Eldelbrock should sell the adapter for the intsalation.
You may run inot low vacume from your cam, IMO, it depends on what cam you have. Ive heard of people putitng vacume bottles to help.

My 67 RS 327...its a work in progress.

the "stock" way of doing it is to hook the power brakes up to the big port on the base of the carb, but if you have a carb that isn't a q-het, then the intake is probably the easiest.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

Your original power brake line should hook right into the power brake vac port on the back of the edelbrock carb. Every edelbrock carb I have done, including 2 that I own now, are this way.

never knew that Travis, but so it is. My 1407 has a port on the front I use with my pcv, and a plugged port on the back.

I did things a bit different. I pluged the power brakes into the manifold tap and the PCV into the rear port on my Holley. Reason is that the Holley's rear port diverts equally to both planes of the manifold. The manifold tap does not. I wanted my blow-by gases to be evenly distributed. I'm not sure how the Edelbrock carb is configured though. I used another manifold vacuum port off the front of the carb for vacuum advance.

It really doesnt matter which one you use either the base of the carb if you have it or the intake port behind the carb they will both do the job fine (depending on your cam providing you with enough vacuum to run the brakes). But I have never seen a difference between the two connections. If you do not have enough vacuum to run the brakes neither port will change that.

All factory power brake installations used a fitting in the top of the intake, just behind the carburetor; all V-8's, all carbs. [img]graemlins/thumbsup.gif[/img]
