Here's my 1978 setup.



Same manifold port as the vacuum line to the EVAP canister (never could figure out why there are two vacuum valves on it, and one seems to be control by the same temp valve as the EGR). I'm not sure where these manifold vacuum hoses go when you switch over to a Holley 390cfm and either Clifford or Offy intake?
