I'm no cam expert. But FYI, the XFi efficiency camshaft has lower lift & duration (and more torque) than the garden variety Metros.
The Olds Turnpike Cruising Package also used an efficiency cam with lower lift, duration and advanced timing.

Both cars did this presumably to permit taller gearing at cruising RPM.
