Old School 509 292 purple shaft cam specs.

[Ramman]

I have an old (1980) single bolt, RB, purple shaft .509 lift 292 duration, direct connection, hyd. flat tappet cam. I've since lost the cam card for valve timing events and lobe separation. I'd heard they redesigned this grind some years later. Does anyone have an old direct connection catalog or complete specs. for this cam?
Thanks group!

If I look around,  I can probably find my cam card.
