    Greetings,
    I have a question about a 1933 OEM intake manifold I purchased (#40- 6520). This intake
    has 2 vacuum ports on it and I just wanted to
    verify that 1 of the ports went to the vacuum
    brake on the distributor and possibly the other
    to a wiper motor?This is a 33' to 36' motor and
    it will be basically stock. It will also have 1 Stromberg 97 carb on it. This motor will go on
    a test stand eventually and not directly in an
    automobile. Any info would be much appreciated.
    Thankyou!

    Yes that make sense...... I agree, but on
    this particular manifold the vacuum ports are the same height down by the intake manifold bolts which I would take to be
    full vacuum from both? I don't have any avenues for vacuum around the Stromberg 97 carb. Thanks!

    I use a homemade hardwood spacer drilled for 1/4" port & tee on my 21-studder for brake & wipers. Plug the two dinky manifold ports.

    That's an interesting way to go about it.
    I will definitely take that under advisement. Thanks Jack!
