2020 GMC Sierra Goliath Harley Davidson by Hennessey
Earlier this year, Hennessey had rolled out the GMC Sierra Denali Goliath 700. The truck came with 700 horses under the hood and transformed the simple Sierra into a magnificent beast. Now, the company has teamed up with Harley-Davidson to roll out another edition based on Goliath. This one features no less than 65 Harley-Davidson specific components in and out. As for the performance, it continues to churn out over 700 horses. As the team says in the video, is this the Harley for a rainy day?
2021 GMC Canyon Syclone by Specialty Vehicle Engineering
We’ve been seeing a lot of revived monikers lately, so why not add one more to the list? This one, however, is revived by an aftermarket company and not the automaker itself. We’re talking about the GMC Syclone that was launched almost three decades back but was way ahead of its time. Specialty Vehicles Engineering, an aftermarket company based out of New Jersey, brought the Syclone badge back last year, and now it is following up with the 2021 model.
The 2021 Syclone is based on the 2021 GMC Canyon.The highlight of the 2021 Syclone is that it has 300 horses more than its predecessor, the 2019 GMC Syclone. We’re talking about 750 horses in a compact truck with a variety of other upgrades and a moniker that set the path to change the course of how trucks are generally viewed. Need we say anything more?
2020 GMC Sierra Denali Goliath 700 by Hennessey
When you hear the name “Hennessey” suffixed to any vehicle, you know it’s going to be a monster in all senses. The company has been transforming SUVs, sedans, and pickup trucks from nimble creatures into absolute beasts since the early ‘90s. Let’s say Hennessey drops massive amounts of gamma radiations into every vehicle to create Hulk versions of them.
The company already deals with the Raptor, Mustang, F-150, and GT, and will soon be adding the 2020 Bronco as well to its portfolio. The company even laid its hands on the Jeep Gladiator and plonked in a Hellcat engine to create a “Maximus” version that makes 1,000 horses. This time around, Hennessey has gotten hold of the GMC Sierra Denali.The power bumps are significant and it looks mighty big with the new raised stance. The company has moniker’d it the Goliath 700. It makes sense, doesn’t it?
2018 GMC 3500HD Denali by Rolling Big Power and Keaton Hoskins
The GMC Sierra 3500HD Denali by Rolling Big Power and Keaton Hoskins is a one-off truck that showcases custom features designed for disabled people. Unveiled at the 2019 SEMA Show, this truck was created by Rolling Big Power, an industry leading manufacturer of aftermarket parts and Keaton “The Muscle” Hoskins from TV’s “Diesel Brothers.” It is based on the older, third-generation Sierra 3500HD Denali.
The truck was built for Jonathan Barber, who was involved in a coal-mining accident in 2017 that left him paralyzed from the chest down. Fitted with a 14-inch lift suspension, this bespoke Denali truck also features a gullwing door, hydraulic chair lift, and twist-handle controls for throttle and brakes, all designed to make life easier for its disabled driver. It’s fancy on the outside and practical on the inside, but it’s also special enough to draw a lot of onlookers at the SEMA Show or other truck-specific events. In other words, it’s a handicap-accessible show rig that we don’t get to see too often.
2019 GMC Sierra by Callaway
There’s no denying that the auto industry is witnessing a paradigm shift. Sedans are dying, EVs are taking over, etc. While this shakedown has affected almost all the segments, trucks have been left unaffected. Their sales are growing every year, and this has given a strong niche for after-market companies to capitalize on. One of them is Callaway, a company that rebuilds these trucks in Connecticut and California. Callaway has been building vehicles for brands like Mazda, Aston Martin, and GM, to name a few. One of the company’s creations has been the GMC Sierra. Callaway has worked on the GMC Sierra 1500 to make it an interesting truck. Are the changes merely cosmetic?
2019 GMC Syclone by SVE
Performance pickup trucks seem to be the trend these days. There’s the Ram Rebel TRX and the Raptor, but this is not a new concept per se. The truck that needs to be credited for making us believe that these butch looking vehicles could actually go fast was the GMC Syclone. It debuted in the 90s and was fast enough to scare the holy hell out of anyone because there was nothing known as ’fast trucks’ back then. However, the truck did not succeed. But, seeing the demand and potential now, the GMC Syclone is all set to make a comeback. The 2019 GMC Syclone is a tribute to the original truck by Specialty Vehicle Engineering, and from what it’s worth, it sure looks exciting.
Redline Motorsports, a Florida based performance shop, just took home the top honors in SEMA’s first international engine building competition. The build-off pitted the Redline team against one of the best-known performance shops in the U.A.E.
Both competitors were selected to compete due to their extensive experience with tuning General Motors’ LS engines – the modern small-block V-8 that powers everything from trucks and vans to Corvettes and Cadillacs.
So the competition went down like this: whoever could build and tune the engine with the highest average horsepower over 10 dyno pulls won. Simple enough. Both teams received identical sets of parts, including new LS3 blocks bored out to 416 cubic inches, performance rotating assemblies, and ported LS3 heads; keeping the playing field level. Separating the teams were their choice of three available camshafts and how they tuned their ECUs.
The competitors were also handed the keys to nearly identical 2012 and 2013 GMC Sierra trucks. The single cab, short bed, 4WD Sierras were both fitted with the stock 6L80E transmission and 3.73 gears. With all the parts in place, the competition rolled into day one. Keep reading below

Leave it to John Hennessey to throw a supercharger and a tune on every V-8-powered GM vehicle. Take this 2015 GMC Yukon Denali. It’s 6.2-liter EcoTec3 V-8 is fitted with Hennessey’s HPE650 Supercharger kit that brings the engine’s output rating to — like the name suggests — 650 horsepower.
The blower is a 2.9-liter unit that is cooled by a high-flow intercooler system, while a set of high-flow cylinder heads help the engine breath. A new camshaft makes adjusts the valves’ operation, adding not only more horses but also a respectable rumble. Lastly Hennessey flashes the Yukon’s ECU with a custom tune. Best of all, the whole deal comes with a 3-year/36,000-mile warranty.
The 650 horsepower and 658 pound-feet of torque is a marked improvement from the engine’s stock 420 horses and 460 pound-feet. That helps the heavy, six-passenger SUV to hit 60 mph in just 4.5 seconds. That’s as fast as a 2015 Mustang GT. The Denali continues rocketing down the strip, finishing the quarter mile in 13.1 seconds at 110 mph. Again, that’s darn close to the Mustang’s 13.0-second, 113-mph run.
Want this sort of power in your new $63,000 mall crawler? Sure you do. All it takes is money. Expect to play close to $20,000 for the HPE650 package.
