Thanks Percy.
I wrote to Dimitri Elgin and he interpreted my cam specs as you can see below. He saw the photos of the lobe damage and said I need a new cam. He recently sold his last blank to another Pantera owner in Northern California and said a new blank may be hard to find but he will try on Tuesday. He also said he made my cam in 1996.
cam specs:
Hyd roller
68x4=272 intale duration, 70.5x4= 282 exh duration
the 10=110 lobe centers
26-66 int, 71-31 exh seat timing
Lobe lift times rocker ratio = gross valve lift. (my rocker ratio is 1.75)
