What happens if ignition timing is too advanced?

If the ignition time is set too advanced then the charge gets combusted during the compression stroke, resulting in the peak pressure achieved inside the engine during the compression stroke. This peak pressure opposes the movement of the piston toward TDC. Thus it results in loss of power and chances of knocking.

Is Vortec the same as LS?

While the performance car engines carried the LS designation, those designed for trucks and SUVs were given the Vortec name. The biggest difference between the Vortec engines and their car cousins was the use of iron blocks (mostly), and the fact that they were often smaller in displacement.
