Chevrolet Silverado

The 2019 SEMA Show may have come and gone, but Hennessey Performance Engineering is still making announcements. Yesterday evening, the company announced a pair of supercharger packages for the T1 2019-2020 Chevrolet Silverado and GMC Sierra 1500 pickup trucks – a feat that’s so far gone unaccomplished. The first package, the Goliath 700 package, produces 700 hp and 711 lb-ft of torque. The second, the Goliath 800 package, utilizes a 6.8L V8 of some kind, producing 805 hp and 812 lb-ft. That’s even more than the V8 F-150 Raptor conversion that Hennessey offers (758 hp), so that’s score one for the GM truck enthusiasts.

Important details for these Chevrolet Silverado and GMC Sierra pickup trucks, such as price, and which engine Hennessey specifically bolted a supercharger onto, are not immediately available. The available photos also appear to be renderings. But even so, there’s plenty of performance specs that HPE has disclosed.
