Hi, I would like to know the proper way to pick a modulator valve and adjust it. The trans came from a 1973 Ford LTD station wagon. It was rebuilt and is going against a hopped up 5.0 roller motor in a 1939 Ford. Right now it has 2 vacuum ports on the modulator. I would like to replace it with a single port . Any ideas? Thanks, Hotrodman
