hiya, new to the forum. i just picked up an immaculate 79 elky with 267. low miles all original, except all the vacuum lines are cut/ plugged. i know most people prefer it that way, but i would like to return everything to just the way chev built it. unfortunately the only vacuum diagrams i can find dont help much. delay valves etc are not marked, or not shown etc. can anyone help me do a scratch reconstruction? i have, charcoal canister, efe on exh, egr, dist. all three switches are in water outlet and manifold, and are working. egr, efe, and vac advance all work. i believe everything will work as new if i can get hoses, delay valves etc, routed properly. thanks in advance for any help.
