With production lasting 14 years between 1973 and 1987, General Motors’ line of third-generation Chevy and GMC C/K pickups, better known as the Square Body trucks, are frequently sought-after for rebuilds and customization. Now, Finish Line Speed Shop in Ellensburg, Washington is showing off its latest 1978 GMC C15 SEMA build, which rocks the pavement with a number of unique touches and a tasty two-tone paint treatment.
The first thing that grabs us about this truck is the way it looks. The classic Square Body lines are in full effect, complemented by a two-tone paint treatment that matches purple and white, enhancing the straight lines and overall rectangular shape of the 1978 GMC C15 pickup. As expected of a modern custom truck from this era, the stance is low to the ground, sitting just inches above the pavement and tucking in a set of aftermarket wheels.
The rollers come with a ten-spoke design and black finish mated to a polished rim, while the spokes reveal a set of aftermarket brakes with drilled and slotted rotors underneath.
This GMC C15 pickup’s cabin space comes with matching purple accents, while the dash gets a familiar gauge layout with two primary readouts behind the steering wheel and an additional four gauges mounted to the left of the steering wheel. Unsurprisingly, modern Kicker audio equipment was also installed to provide the tunes.
The good stuff continues under the hood, where we find an LS V8 engine on deck for motivation. The GMC C15 pickup’s new LS was upgraded with Hedman Ceramic headers, while various engine covers and trim bits were dressed up to provide a little extra visual appeal. We also spot a Wilwood aluminum master cylinder to coincide with the upgraded brake package.
On the move, this custom 1978 GMC C15 pickup looks fantastic, but it also sounds equally as good when dipping into the throttle, as evidenced in the following video.

Color scheme is so-so.
Lowered with the “ghetto” wheels takes away from a nice truck.
Way too many decals , lame.
Seems like everyone & their brother are swapping in LS engines.
Big Block or an old W engine 348/409 would be much cooler!
Maybe an Olds 455?
It’s custom. A thing that’s been going on since chariot days. even if we go to EV’s people will still want personalization. I’ve been in it all my life, 60 plus years, and have never seen it so diverse as it is now. Good for our industry and hobby. LS engines are getting hammered by the knowitalls because everyone is doing it. There’s a reason for that. Still, anyone can do whatever they want. Can’t with to get my 37 Chevy delivery with a built 292 Jimmy on the road. And yes it will blow the doors off anything made now. The main thing is with automotive individualization (or not) we all just do whatever it is that sparks our love and we all remain united.
Looks great .. the beauty of individualizing your ride. Does anyone know the color code for that purple ? It’s for and older musclecar project. Thanks !
