HELP figuring cam lift ( maybe actual purple shaft p/n?

The cam is used. I bought it in an engine and was trying to decide to use it in my 383 build. It sounds like it's a lot bigger than I want to put in the car. I may have it reground or sell it with the lifters if I can figure what exact size it is.
Advance it about 8 degrees or so, like to 100, you'll love it.
