Where do you get the vacum for modulator valve on the 400. Does it come off the manifold or the carb? please advise as I think it should come off the carb. Only fiting I have for vacum from the carb is vacum advance to the distributor.

Thanks in advance.

Thanks a bunch. A buddy said that would be to much vacum for the modulator. Glad I asked. Was concerned abou the hook up since I only had one vacum line off of the carb and it was going to the distributor.
