Yep.  In general, that's the idea - more low end torque though sometimes it will increase torque output across the cam's usable RPM range.

Gnarly - plug a cam in to your dyno sim program straight up, then advance it 4 or 6 or 8 degrees and watch what happens.

Here's one LCE cam that has 8 degrees of advance ground in. Their website lists all the lobe position specs for their cams and there are several other grinds with varying amounts of advance ground in.

Hey Plainview,

I'm not trying to be a butt-head with my questions, but really just curious about what published specs on a supplier's cam means to the average buyer.  And, then what cam timing does to the valve opening and closing events.

How did you determine the cam timing of the LCE cams with ground in advanced?  Where in their specs do they publish CAM TIMING?  Where in their published specs do you see OVERLAP DEGREES?

If you see the Lobe Separation Angle in the cam spec, will that tell you the Intake Centerline?

Geezzz…I’ve played with cam timing in the EA software a zillion times!

Gnarls.
