This site is dedicated to 82-92 Camaros & Firebirds.
Someone here MIGHT know the info your looking for, but good luck. You'd have better looking on a site dedicated to older cars.

Re: 1971 CHEVELLE 307 ENGINE 2BBL VACUUM HOSE ROUTING
i know the way i have it on my 4bbl is a hose from the pvc valve in the valve covers to the carb and brak booster, and a seperate line from the carb to the distributor. Then theres a vaccuum port on the intake manifold that goes to the transmission (if your running a th350), and one to the grommet in the firewall that has 2 hoses coming out of it. The second hose from that grommet goes to the heater core shutoff valve that comes off the intake manifold.
Hope this helps
