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

If you had to have a MP cam for that, and it had to be a SFT, and if they were still budget friendly(and actually available), that really sounds more like a place where a .528 cam would be a decent choice(as opposed to the .557).
I’d use the specs of one of those and look for something similar that’s readily available.
Man, I need to learn not to post with half a cup of coffee ingested... yes, sorry, the 528 is more in line. I'm likely going to sell this and contact Ken at Oregon Cams after I get the compression figured out.
