I am nearing the end of my engine swap and have a question on the vacuum lines. What should be connected and where. I have power brakes, and A th-350 transmission with an electrical detent switch. I noticed another vacuum hose that runs to the transmission as well, is this suppose to be hooked up. I have a 650 holley carb, I know the vaccuum advance from the distributer should run to the carb. I guess the question I have is I want to make sure I hook up the right lines, to the right places. I know an EGR? fitting to the valve cover was there on the old engine, do I need to hook another one up or just use breathers. I have two holes on one valve cover and one on the other. Sorry for all the questions, but want to get it right, before firing it up. It is a vortec 383 chevy. Thanks in advance.
