3 bolt cam gears.
Example.... Type b .. Dot to dot will set the cam straight up. While, type c ... Dot to dot will retard the cam 8 degrees.
Anybody?

The VVT stuff, on the other hand is like that. Not to mention there were two different cam cores which were also phased differently. I'm pretty sure LC9's had VVT though, at least mine did.
