{{Short description|Line of gasoline truck engines}}

'''Vortec''' is a trademarked name for a line of gasoline engines for General Motors trucks. The name first appeared in an advertisement for the 1985 model year 4.3&nbsp;L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air / fuel atomization.<ref>[https://jl-discourse-uploads.s3.amazonaws.com/original/2X/4/450304d1f4f1bdce16fd8490bfa40a315db0df19.jpg 1985 advertisement]</ref> It has since been used on a wide range of engines. Modern Vortec engines are named for their approximate displacement in cubic centimeters.
