PCV can go on the rear runner nipple
Wrong, unless you want to make #6 cylinder run lean because you're trying for a shaky idle and pinging and eventual damage in that cylinder! The PCV needs to connect to the intake manifold plenum. Any carburetor originally intended for a post-'62 Chrysler product (and some before that) have the PCV port on the throttle body. If a non-Mopar carburetor is used, a port can be drilled and tapped into the plenum. On '73-up intakes with EGR provisions where EGR is not being used, the blockoff plate is a perfect location for drilling and tapping in the necessary nipple.
Kenicb: You've got a '70 California + '71 50-state/Canada fuel pump on that engine. The nipple on the body should be connected to the carb's bowl vent (top front connector, where your PCV hose is presently hooked up). The PCV hose should go to the carb's PCV inlet nipple, on the passenger side near the bottom of the carb, which you've presently got connected to the fuel pump body nipple. Basically you just need to swap the positions of the two large hoses connected to the passenger side of the carb. Do it pronto, then reset your idle mixture and speed.
EGR blockoff plates go by on eBay all the time.
