Background

Each Vortec engine has a four-digit number following the name that denotes its displacement size. A Vortec 5700 displaces 5.7 liters.

In Name Only

Although all GM engines carry the Vortec name, many are unrelated and don't necessarily share the same parts or design, according to gmhightechperformance.com.

Displacement on Demand

The optional "Displacement on Demand" Vortec 5300 5.3-liter V-8 can shut down up to half its cylinders under certain driving conditions to save fuel, according to conceptcarz.com.

Standard Engine

GM's standard engine for its trucks is the Vortec 5300 5.3-liter V-8 featured in Cadillac Escalades, Chevy and GMC vans, its SUVs and all GM pickup trucks, according to novak-adapt.com.

Vortec 6200

By 2007, GM produced its heavy-duty all-aluminum 402-horsepower Vortec 6200 6.2-liter V-8 for the Escalade, the Chevy Tahoe, the luxury GMC Yukon Denali line, the Hummer H2 and the Silverado 1500 pickup.

Marine Use

The Vortec 8100 8.1-liter all-iron V-8 is GM's largest motor, which generates between 225 to 340 hp. It's no longer used in the Silverado pickups, but is used as a marine engine with horsepower boosted to 500.
