Looking for info on a Manley big block cam 17383

Looking for specs on this old Manley cam out of a 440. Only markings I can find are shown.
"Manley" and "17383" on the snout, and it looks like "107" on the shaft, a few paint bands and dabs.
I believe it is a "Thunderstick" , but am coming up dry searching the internet, including Manley's website, so far. Has anybody run one of these cams? I would love to see a cam card!

Thanks!
