  1. 390 Waterpump bypass nipple, intake side

    Big Block Roadster Builds
    I have changed the manifold on my 390 to an Edelbrock Performer RPM. The bypass nipple is missing on the manifold. I understand they have to be pressed in. Can anyone fill in some of the details to make this happen. My hope is that I will not have to remove the manifold.
