I've attached the most to date list of Shovelhead cams that I have. I'll update as any new information is found.

Do you have the XLSX version of this file? It makes it easier to do side-by-side comparisons. Thanks

All the big twin cams on file are listed in the interactive calculators and charts section.

Do you mean these two Dave Mackie Shovel cams that are in the Shovel section?

Ohio the first post only showed his M8 cam . All good mate 

That's because that is the M8 cam page. You have to click on Shovel at the bottom. Like I said, all Big Twin cams we have on file are there.

For the people who want a stock replacement cam for their Shovelhead or Panhead, S&S offers the H-grind.
330-0166 1978-1984
330-0165 1970-1977
330-0170 1958-1969
330-0164 1948-1957

I always wondered who was right with the H cam specs, S&S or Andrews. They differ a little in what they list.

In my old 1999 Andrews catalog they say their "H" grind is closer to H-D's later model "S" grind. I can't find the specs for the H-D "S" grind in my limited resoueces.

For what it's worth I always liked the way the Shovels ran with the "S" grind. Better low end mid range.
