What distributor was used on the 1972 351C-4V Torino with automatic transmission?

The 49-states 351C-4V automatic Torino used distributor D2ZF-GC, with centrifugal advance of 0-1/2° at 500 RPM up to 8-1/2–11° at 2000 RPM, and vacuum advance of 0-2-1/2° at 5 in. Hg rising to 6-1/2–9-1/2° at 10–20 in. Hg.

How is the distributor test stand set up for the centrifugal advance figures?

The test stand is set to 0° at 250 RPM and 0 inches Hg; advance is then read in degrees at 500, 750, 1000, 1500 and 2000 RPM.

What are the vacuum advance specs for the 351C-2V automatic (D2AF-KA) in Torino/Montego/Ford?

0-1° at 5 in. Hg, 2-1/2–5-1/2° at 10, 6-1/2–9-1/2° at 15, and 10-13° at 20 inches Hg (test stand set to 0° at 1000 RPM and 0 in. Hg).

What do the footnote symbols on the 429 and 460 rows mean?

① means "With 3.0 Axle" (460 D2VF-BA Mark IV) and ② means "All except Thunderbird" (429 D2MF-EA). M = Manual, A = Automatic transmission.

Are separate distributors listed for California cars?

Yes. The Distributor Number (12127) column is split into 49 States and Calif. versions; for example, the 200 CID manual uses D2DF-CA in 49 states and D2DF-EA in California.

This two-page scan (pages 26–27, Group 23 – Ignition System) presents Ford factory distributor specifications tables for the 1972 model year (all distributor part numbers carry the D2 prefix, indicating 1972). Each row lists an engine (1600cc, 2000cc, 2600cc, 170, 200, 240, 250, 302, 351W, 351C-2V, 351C-4V, 351C-HO, 400, 429, 429 Police, 460), the distributor part number (basic part 12127) for 49-state and California applications, transmission type (M-Manual, A-Automatic), and applicable car lines (Pinto, Capri, Maverick, Comet, Mustang, Cougar, Torino, Montego, Ford, Mercury, T-Bird, Lincoln, Mark IV). For each distributor, three test-stand curves are given: centrifugal advance in degrees at 500, 750, 1000, 1500 and 2000 RPM (test stand set to 0° at 250 RPM and 0 in. Hg); vacuum advance in degrees at 5, 10, 15 and 20 inches of mercury (set at 1000 RPM, 0 in. Hg); and vacuum retard in degrees at the same vacuum points. Footnotes note the D2VF-BA 460 distributor applies with a 3.0 axle and the D2MF-EA 429 covers all except Thunderbird. A mechanic can use this to verify or recurve a 1972 Ford distributor on a distributor test machine.
