Last year, Hennessey announced its new Goliath supercharged upgrade kit for the Chevrolet Silverado 1500 and GMC Sierra 1500.
The Hennessey Goliath package pumps the 6.2L L87 V8 engine up to 700 horsepower thanks to a 2.9-liter supercharger and other upgrades such as a cat-back exhaust, high-flow induction system, Chromoly hardened pushrods and HPE engine management calibration. The Texas-based tuning shop claims the truck will accelerate from 0 to 60 mph in just 4.3 seconds – quite a significant jump from the 5.4 seconds it takes for the standard 6.2L-equipped Silverado 1500 to reach 60 mph from a stop.
While these numbers all sound good on paper, the best way to prove just how fast the Hennessey Goliath 700 upgrade kit can make the Silverado 1500 is with a true demonstration. Luckily for us, that’s exactly what Hennessey did this week, uploading a video showing a stock 6.2L V8-powered Silverado 1500 drag racing a Goliath 700-equipped model.
Not surprisingly, the Hennessey-tuned pickup crushed the stock truck by some margin. We have to hand it to the stock Chevrolet Silverado, though. While it may not have the muscle of the supercharged truck, we were impressed with the naturally aspirated 6.2L V8’s performance. It’s safe to say that for the average person, the 6.2L L87 V8, which is rated at 420 horsepower and 460 pound-feet of torque from the factory, is more than enough for most buyers.
The Hennessey Goliath 700 truck in the video does not feature some of the other upgrades the tuning company offers for the Chevrolet Silverado and GMC Sierra, which include 20-inch Hennessey alloy wheels wrapped in 35-inch Toyo off-road tires, a six-inch lift, a custom Hennessey front bumper and an LED light bar, among other things. These upgrades (mainly the larger wheels and tires) would make the truck a bit slower, so for Hennessey, it makes more sense to use a truck on stock wheels and tires for this comparison test.
Check out the video embedded below to see the Hennessey Goliath 700 race a stock Silverado 1500 mano-a-mano. Hennessey also offers an 800-horsepower ‘Goliath 800’ upgrade kit for the 6.2L Silverado, too, so we’ll also be waiting for a head-to-head race with the more powerful truck as well.

That’s awesome. The 6.2L NA engine is no slouch either.
No, it’s not. The gap wasn’t getting bigger after black one pulled away.
Make it a true test of vehicle, switch drivers and run it again. Only one driver and one run is not a true test.
