the carb put on my street motor has no vacuum port

No DO NOT touch the carb..get a 1 inch aluminum spacer plate..GO WITH 2 INCH if you got hood clearance ..some come with a vaccum port but you can drill and tap one no problem..tap it and run you a 3 way if you need more than one vaccum port.
( make sure you get the plate for the 4500 series dominater)

what Ed said above couLd hold very true if your motor has any kind of hot cam in it at all..if this turns out to be the case..i will tell you how to solve it now..They make a canister that will allow you to build vaccum,,you will plug your brake booster into the back of this canister and whamo you have brakes ( very easy to hook up) basic tools will allow you to assemble..i had to use one of these on a 89 pro-street outlaw car i had 4 years ago...it is a common problem that street cars run across with hot street motors with LARGER CAMSHAFTS...so don't freak out if you tap your plate and still do not have enouigh vacccum to operate the brake booster..
ohh yeahh
they sell these kits at JEGS/SUMMIT...ETC....

Exactly what bjuice said, I have one of these canisters I used to run. It really works good. Mounted mine right over the old wiper motor location.

if you got one of them hard plastic spacers, you can still drill and tap it for a fitting....no need to buy a new spacer...

I had same problem with my ultra hp 950dbl pmp.I run a 434 with a solid roller on a 108.I run vacuum canister,and I drilled & tapped intake manifold just below rear bowl.I use a supervictor,& it looks like it was made with my custom port.(he,he)Had no choice,car is second gen. Camaro,no hood clearance.I had to run a tee with one large opening (power brakes)&one small(modulator valve THD350).Anyways,no issues looks & works great.
