360 Stock Cam Spec's.?

They really put some small camshafts in the 360 starting in the mid '70s, in order to meet smog requirements. In California, where I live, can you believe that they even had to add an air pump to the 252/252, .410/.410 cam in order to make it meet smog! However, I have found empirically that a California LA motor with an air pump will pass smog with a Mope Perf P4452759 dual-pattern cam, which has a duration of 260/268 and lift of .430"/.450". That's still a pretty small cam, but it runs quite a bit better than the 252/252 with only .410 lift.
