Re: HELP.. Intake Manifold Install..HELP
I have the same carb as you and I went to the holley web site to figure out the vac lines. There are 4 vac ports on the carb and the site says that the large port on the side of carb (near the secondary diaphram) is for power brakes, the small vac port on the upper part of the primary metering block is for the distributor, the large port on the front under the primary float bowl is for pvc, and the small port right next to this is for any other vac accesory you may have (I used it for a vac guage in the dash). so I just plugged the port in my manifold and used the ports on the carb. Here is a site that has the full manual for the carb there is diagram on page 6 that will be useful to you. http://www.scribd.com/doc/9376128/Ho...buretor-Manual
