1. What is Vortec?  

"Vortec" is a brand of GM Powertrain engines that delivers more horsepower and greater
fuel efficiency than comparable competitors engies. The name Vortec originated in the 1986
4.3 V-6 engine that used a combination of "vortex" and "GM technology" to create a
vortex inside the combustion chamber. GM Powertrain engineers incorporated this
phenomenoninto their engines to achieve a better air-to-fuel mixture in the combustion
process. The result is what has now developed into Vortec Engines; engines with significantly
increased horsepower and improved fuel efficiency.
