From Dodge, Plymouth and Chrysler Police Cars, 1979-1994 Sanow, Bellah and Govier:
"as a comparison, the 1974-6 E58 4 BBL HP cam has a lift of .429 (I) and .444 (E) and 268 duration. This is Mopar cam #4214671. The 1977-80 360 4 BBL cam was a bit milder due to the emissions crunch. They had the same specs for both intake and exhaust at a .410 in lift and 252 degree duration."
So looks like by 1977 the .430/.444 cam was gone.
