The M8 in the serial number is December, 1988, so it's likely a 1989 model year World. HERE's
the 1989 World catalog page.
The World, Sprint, and Caliente were at the bottom of the road bike heirarchy, so specifications were not included in the catalog for these models. HERE
are the '89 road bike specs, and although the World Sport had 4130 chromoly main tubes, I believe the World, Sprint, and Caliente had straight gauge 10XX carbon steel frames.
Science doesn't care what you believe.
