Jerry,
And, to add more confusion, the '71 had two different emissions placards.
The first placard is from my car, s/n 1490.
The second placard is s/n 2071. I'm guessing here, but this may have had a dual point distributor.
The third placard is s/n 2806. This does have the dual point distributor. In 1972, the C/R was dropped to 8.8, which resulted in a considerable HP loss. Ford tweaked with the cam and timing in an effort to try to regain the loss, but their efforts fell short.
