There has arguably never been a better time than now to be a pickup truck fan. Not only are these vehicles more capable than ever before, but automakers aren’t afraid to have a bit of fun with these profit-driving products. This is particularly true in the off-road segment, where Ford, GM, and Ram are all battling for dominance out on the trails. That said, none of these companies offer anything in the way of a muscle truck anymore. Thankfully for enthusiasts, the aftermarket has stepped up to fill this void. Take the Callaway Silverado Signature Edition for example, with its supercharged L87 V8 engine. Now thanks to Callaway Cars, we have a chance to see and hear what this new-aged muscle truck is like out on the road. Spoiler alert: it’s way more raucous than a standard T1 Chevrolet Silverado.
The Callaway Silverado Signature Edition starts life as either a Trail Boss, RST, LTZ or High Country model, complete with 4×4 and the ever-important 6.2L V8 engine. From there, the tuning shop straps the T1 pickup truck with an Eaton TVS R2650-based blower. Alongside the forced induction comes a high-flow intake system, a stainless-steel dual-outlet exhaust with quad tips, and a unique engine calibration. That helps bring total output up to 602 horsepower and 560 lb-ft of torque at the flywheel. For those keeping score at home, those are increases of 182 horsepower and 100 lb-ft of torque over the factory ratings. Thanks to that added performance, the truck is now able to go from 0-60 mph in just 4.3 seconds, before running the 1/4 mile in a mere 12.5 sec at 113 mph. Not bad for a half-ton.
As this short video clip highlights, the Callaway Silverado Signature Edition sure sounds like a genuine muscle truck. That said, it isn’t surprising that the combination of a supercharged V8 engine and a Callaway Cars exhaust sounds the business. The truck looks quick too, which isn’t always easy to capture on video.
The Callaway Silverado Signature Edition package rings in at $27,995, excluding the cost of the donor vehicle of course. The package includes more than the engine modifications however, as you also get unique interior treatments, carbon fiber engine dressings, and a choice between two different Callaway Cars wheel options. Furthermore, the package is also covered by both the factory GM warranty, as well as Callaway’s own 3 year / 36,000 mile limited warranty. That should add some extra peace of mind when you’re out tearing it up with your supercharged T1 Chevrolet Silverado.
