1979 Chevrolet K10 Silverado

Project
Bill's Banshee

The build that defines Headwaters Customs.

The Story

Vintage Soul. Modern Muscle. Montana Made.

Some builds are about transportation. Some are about nostalgia. Project Bill's Banshee is about neither — it's about what happens when you take one of the cleanest square-body bodies ever made and give it the drivetrain of a modern performance SUV, then add another 500hp. You get something that's unadulterated. Something that screams down the road that is accurately described by nothing better than, well, a banshee.

The foundation is a 1979 Chevrolet K10 Silverado — a truck that already had presence in factory form. The two-tone blue paint, the chrome trim, the Silverado badge — all of it preserved and restored to a standard that makes it look like it just rolled off a GM show floor in 1979. Except it didn't. It rolled out of Headwaters Customs in Ennis, Montana.

Under that classic hood lives a 6.0 LS bored and stroked to 408 cubic inches, force-fed by a turbocharger to produce an estimated 1,200 to 1,300 horsepower. The entire truck rides on a full all-wheel-drive Denali chassis — modern geometry, modern braking, modern everything — wrapped in a body that looks like it belongs in 1979.

The LED headlights, custom billet grille, and chrome wheels are the only tells. Everything else is period-perfect. That's the point. Bill's Banshee doesn't announce itself. It just goes.
