General Motors unveiled the fully refreshed 2022 Chevy Silverado 1500 in September, introducing a long list of updates, changes, and upgrades for the highly-popular light-duty pickup truck. Among these was a torque boost for the turbocharged 2.7L L3B gasoline engine, which is now rated at 420 pound-feet at 3,000 rpm. However, that figure may in fact be underrated.
GM Authority has learned from sources familiar with the matter that the turbocharged 2.7L L3B gasoline engine in the fully refreshed 2022 Chevy Silverado 1500 could actually produce an SAE-certified 430 pound-feet of torque, rather than the 420 pound-feet announced previously.
We reached out to General Motors for comment, however, the automaker reiterated that “maximum torque is GM-estimated at 420 pound-feet (569 Nm) for the 2.7L Turbo High-Output engine.”
As a reminder, the L3B engine – initially introduced for the overhauled 2019 Silverado 1500 – is offered in High-Output form for the refreshed 2022 Chevy Silverado 1500. Prior to the 2022 model year refresh, the L3B engine was officially rated at 310 horsepower at 5,600 rpm and 348 pound-feet of torque at 1,500 rpm, while the refreshed model is currently officially rated at 420 pound-feet of torque at 3,000 rpm. Horsepower ratings remain identical at 310 between the pre-refresh 2022 Silverado 1500 Limited and the refreshed 2022-model-year vehicle. In fact, the high-output L3B engine replaces the naturally-aspirated 4.3L V6 LV3 and 5.3L V8 L82 engines to becomes the standard base engine for the refreshed 2022 Silverado 1500 WT, Custom, Custom Trail Boss, LT, RST, and LT Trail Boss models.

|2019-2021 Silverado 1500||Atmospheric 4.3L V6 LV3||285 @ 5300||305 lb-ft @ 3900 rpm|
|2019-2021 Silverado 1500||Atmospheric 5.3L V8 L82||355 @ 5600||383 @ 4100|

|2022 Silverado 1500 Refresh||Turbo-charged 2.7L I4 L3B High Output||310 @ 5600||430 @ 1500|
Further updates for the 2022-model-year refresh include new exterior styling, which GM Authority was the first to tell you about, as well as a completely overhauled cockpit on the LT trim level and above.

In addition to the High Output 2.7L L3B, the fully refreshed 2022 Chevy Silverado 1500 is also offered with the naturally-aspirated 5.3L V8 L84 gasoline engine, the naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax. The truck rides on the GM T1 platform, with production taking place at the GM Silao plant in Mexico, the GM Fort Wayne plant in Indiana, plus the GM Oshawa plant in Canada later on in the model year.
