I am going to test my engine in the morning and need to know what to do with the vaccum connections on the Carburetor. It is a 350 with an edelbrock carburetor. This truck goes into the body shop for Body and Paint on Monday and I need to fire the engine prior to that. No sense in major engine work or engine swap after a nice paint job. I also read a thread one time about all the things that needed to be done to test fire an engine that doesn't have the complete electrical hook-ups inside the cab. Everything is stripped down for paint. All I need is the good feeling that the engine rebuild was successful. Is there such a thing as a vaccum diagram? Thanks for your help like always.
