    Hey everyone, I have a 327 in my 32 Ford running 3 Rochester carbs, My question is the vacuum port on the center carb with a " T " fitting drawing enough vacuum to operate the power brake booster mounted on the frame and the PCV valve ? Their is another port on the manifold but it goes to the modulator on the Trans. Engine has a small cam nothing wild. Thanks

    I'm thinking that there is a factory Chevrolet Vacuum T that fits on that #8 runner that splits the vacuum to the booster and modulator. That may not have more vacuum but it might have a more consistent vacuum level.

    Might also consider a vacuum reserve can that can provide extra vacuum on demand...

    You might consider a separate constant electric vacuum pump.when the ignition is activated

    MR48CHEV has the right idea find the factory tee has a 3/8'' port on one side and an 1/8'' on the other side goes on the back of the intake.

    Okay I'll try that but which one goes to the trans. and which one to booster ? I did see that port on the back of the intake but only has one 90 deg. fitting going to trans. Thanks again
