The 2021 Chevrolet Silverado 1500 pickup truck is no longer available to order in the Custom trim level with the naturally aspirated 4.3L V6 LV3 gasoline engine or naturally aspirated 5.3L V8 L82 gasoline engine. As such, the 2021 Chevrolet Silverado 1500 Custom is currently only available to order with the turbocharged 2.7L I4 L3B gasoline engine.
GM Authority was the first to report the limited engine lineup for the 2021 Chevrolet Silverado 1500 Custom back in January, with the LV3 and L82 dropped, leaving the L3B as the lone engine option. Interestingly, this reflects General Motors’ decision to drop the LV3 and L82 from the Chevy Silverado 1500 engine lineup for the 2022 model year, as GM Authority reported earlier this month.
GM Authority originally questioned the longterm prospects of the 4.3L V6 LV3 earlier this year. In December, we provided a comparison of the LV3 to the turbocharged 2.7 I4 L3B, shedding light on the L3B’s greater power and torque, fuel efficiency, acceleration, and max trailering. As noted before, the transmissions used play a factor, as the LV3 pairs to a six-speed automatic and the L3B pairs to an eight-speed automatic, but the turbocharged engine and high-tech valvetrain play the biggest role.
As a reminder, the naturally aspirated 4.3L V6 LV3 produces 276 horsepower and 298 pound-feet of torque, while the naturally aspirated 5.3L V8 L82 produces 355 horsepower and 383 pound-feet of torque. By comparison, the turbocharged 2.7L I4 L3B produces 310 horsepower and 348 pound-feet of torque.
For now, 2021 Chevrolet 1500 Custom Trail Boss and Work Truck trims still offer the 4.3L V6 LV3 and 5.3L V8 L82.
It should also be noted that General Motors is currently producing units of the 2021 Chevrolet Silverado 1500 and its corporate cousin, the 2021 GMC Sierra 1500, with the 5.3L V8 L82 engine, but without Active Fuel Management technology, as GM Authority covered previously.
