Vacuum Lines Routing

Need some more help. I put a 350 small block (87-95 4 bolt block) in a 69 I am redoing. Put in a Mallory series 85 Dist and a Edelbrock 750 Performer carb. I do not have a clue where the vacuum lines go. I have a port on the Dist, Two on the carb. Manuel says to only use one of the ones on the carb. One is for timed vacuum and the other is for full vacuum. says to use one and cap the other. No emission stuff just a hole in manifold cover for PCV and port on carb for PCV hose. No power brakes and is a 4 speed.Can someone tell me where thes lines start and end and which port do I use, timed vacuum or full vacuum. Any help is appreciated. Thank you.

Re: Vacuum Lines Routing

Drivers side vacuum port on the carb will be full manifold vac. that is the one you want to use.

Re: Vacuum Lines Routing

Thank you.. Where does it go to from the carb. A port on the manifold or the distributor ?

Re: Vacuum Lines Routing

Thank you that takes care of that line. Still need help ,Am I correct to put a PCV in the rear 3/4 " hole of the valve cover (passenger side) and run 3/8 " line to the port on the carb ? Then one more question. There is a threaded hole directly behind the carb (about one inch) on the manifold, Slightly to the passenger side. Looks like 1/2 " pipe thread . Is this for a sensor or more vacuum ? Can I just plug it ?
Thanks again.

Re: Vacuum Lines Routing

Mine is plugged, it's a port for the power booster for power breaks which can also be used for other things.
If your valve covers have a hole in the drivers side cover, put the pcv in that one and run to the line to the big barb on the front of the carb.
