Two cam profiles were used in most 440's.
These are listed from my 1971 Factory Service Manual:

The Standard 350 HP cam specs:
260/268 Duration, 0.425"/0.435" lift, 38 degrees overlap (113 LSA), installed at 112 Intake CL.

The HP 375 HP cam specs:
268/284 Duration, 0.450"/0.458" lift, 46 degrees overlap (115 LSA), installed at 113 Intake CL.

I have a '74 FSM for the dodge trucks, and it also listed the 268/284 HP cam as the cam used in the 440 for that year. I don't have a 1977 Factory Service Manual, so I can not be sure of the cam specs, but it is likely the same since the cams above seem to be the only stock replacement ones avaliable?
