Hi, I am new here and searching for engine data.
Most of the places I see say that the stock cam for:
383/335 Magnum
440/375 Magnum
440/390 6v
was all the same cam, 1967-1971, manual or automatic.
Most places I see give the duration at .050 lobe as
228-241
Lift .450 .458
Is that true for all years?
But Clevite shows another cam for "383 & 440", CLV-2323,
383 4bbl 1968-1971
440hp 1968-1978
With a duration of
213-225
Lift .447 .459
That is quite a bit smaller, but the lifts are so close I am confused, are the 213-225 and the 228-241 the same cam? If so, who is right?
Where was this smaller cam actually used?
I'm guessing maybe on the 1972-up 440hp for smog?
Anywhere else?
Thanks very much, I tend to shy away from "advertised" durations as they are often arbitrary.
