What is a “Vortech” engine???
In the past, when someone decided on an engine there were the inevitable regrets: “It’s got great horsepower, but the gas mileage is poor,” or “It’s very durable, but it can’t tow much,” or “It gets great mileage, but it requires a lot of maintenance.” Vortec engines are designed to deliver great horsepower, with excellent fuel efficiency, impressive durability and low maintenance requirements. The Vortec name reflects the powerful vortex in the combustion chamber and the sophisticated technology that GM uses to maximize both performance and efficiency. The name “Vortec” originated in the 1986 4.3L V-6 engine that used “vortex technology” to create a vortex inside the combustion chamber as pictured to the right. GM Powertrain engineers incorporated this phenomenon into 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 that are designed to deliver plenty of horsepower without sacrificing f
