The service manual for 1970 big blocks concerning the correct wiring for the distributor vacuum advance isn't as helpful as pics of original engines and restored engines. Who here can help the rest of us out with pics of engines without their air cleaners installed, specifically asking for pics of how the vacuum advance is wired for all 1970 383 2bbl & 4bbl, 440-4bbl, and 440-6pk's built after Jan. 1, 1970.

NOS vacuum advance units typically include these two wires (black/female spade & blue/male bullet)- my guess is there was a variation or two concerning these wires.

Thanks Moparts and all its members!
