Chevy 4.3L Vortec Engine

The Chevy 4.3L Vortec (4300) is a family of six-cylinder small-block gasoline engines introduced by General Motors in 1985 and phasing out in 2022. The Chevy 4.3L Vortec is the longest living and most successful of the Vortec engine family. While the general make-up of the Chevy 4.3L Vortec engine remained the same over its 40-year production history, there were several upgrades and changes to components and features over the years.

Chevy 4.3L Vortec Engine Overview

In 2014, Chevy launched two different engine models. Older engine models dating back to 2013 were used in sports cars and trucks, and they produced 155 horsepower and 230 lb-ft of torque. The new engines, which came out in 2014, offered more power and better fuel economy. They are featured in Chevrolet full-size trucks and vans.

The Vortec engine name comes from the word “vortex,” because GM designed the engine to create a pressurized swirl, like a mini-tornado, within the combustion chamber to efficiently blend gas and air together. This vortex enabled the engine to produce more power while still being relatively fuel efficient.

The first variant of the Chevy 4.3L Vortec engine line, known as the LB1, only lasted one production year. It was used on Chevrolet and GMC full-size pickup trucks and vans, but had a different injection system than the engine used in General Motors cars, such as the Chevrolet Caprice, Chevrolet El Camino, and Pontiac Grand Prix. The LB4 variant featured several changes to increase power and was expanded to power Chevy Silverado and GMC Sierra trucks.

The Chevy 4.3L Vortec engine family was discontinued in the mid-1990s and only continues to be produced for pickup trucks, vans, and sport utility vehicles.

The EcoTec3 V6 engine is a newer design that was prominently featured in the all-new 2014 Chevrolet Silverado and GMC Sierra full-size trucks, as well as Chevrolet Express and GMC Savana vans. It features a new multipoint fuel injection system that boosts performance to 285 horsepower and 305 pound-feet torque ratings. However, gas consumption remains high at 16 miles per gallon.

General Motors plans to retire the Chevy 4.3L Vortec engine in 2022 when releasing the Chevrolet Silverado 1500 and GMC Sierra 1500. This engine is currently found in the Ford Ranger and Toyota Tacoma, both of which will be discontinued at that time.
