Vortec or LS?
What are these engines? Are they LS or Vortec? I've seen and heard that the LS are actually Vortecs but the LS doesnt look anything like a Vortec block as there are no lifter trays. ALso if the LS is a Vortec the 2002 Gen 1"LS1" cant be a Vortecas the "Vortec" was around before the Gen1 LS1. Whats going on here?

Vortec is just a name that they used to describe the heads. It's supposed to make you think of a vortex which is a powerful air movement. It has nothing to do with anything but the shape of the domes in the head. The Vortec heads are on any engine found in a gm truck including the 6 cylinder in the s10 in the mid 90's
