Variable Cam Timing (VTC) is completely different from Variable Valve Lift (VVL.)

VTC can vary how long the cam keeps the valve open (up to like 25* IIRC), VVL changes how far the valve open by using a second set of cam lobes (think VTEC.)

I wasnt correcting you, just making sure Rhart doenst get them confused since SR's came with both types.
