Cam Spec Question

IDK, but
All I could find is that it was supposed to be .415/.425 lift and seems to compare to an early 360 2bbl cam.
The 360-2bbl cam,IIRC, was 252/260/112, but I honestly don't recall the 273-4bbl specs.
And the 4 barrel specs changed a little between 65 and 66. @65dartcharger would know I bet.
