A member named "03limited" was a big fan of that camshaft, if you search around for "mudbuster" in the forum you should find more than a few instances of him talking about it.
Sky High, you can find that with a search too, but it's easier to explain because I've run it before. You flip the rear section of the linkage upside down, this alters the rear shock's lower mounting point, changes geometry a bit, and lowers the rear end. Not recommended for jumping.
