Old Isky Cam help?

What are the chances someone has an old catalog or list of Isky big block cams from the 1960s? I know it's a long shot but trying to find the possible cam my grandpa used in his 426 street wedge that helped him bump it up into factory experimental back in the mid 1960s. He thinks it was cam the "310 Isky" if that helps?
Probably was their 300 series.
They made good power for what they were.
I'll look see if I have anything on those cams. I know they have them listed in old paw catalogs
