Looking for info on a Manley big block cam 17383

It's a fresh build for a drag car, that's been sitting 25-30 years. Yeah, I figured 107 might be the LSA. Nick did all the engine work for Ed Hamburger back in the day. I'm sure he used it for a reason. I was just hoping to find specs, or maybe even a cam card while I'm waiting to hear back from Nick.
According to the internet, this cam don't exist, lol! I'll probably call Manley, too.
It's a super cool old school grind. Lots to be said for that. I think you have a diamond in the rough.
