Josh Wojciechowski has already spent plenty of time chasing tenths in a truck.
Most LS Fest regulars know him from his F-100, a truck he has owned for around 10 years and raced for seven seasons across LS Fest, Pro Touring Truck Shootout, and Optima’s DriveUSCA events. It worked. It was fast. It was also expensive and stressful.
“I’ve learned that not being so competitive is more fun,” Josh said. “That’s what this truck is about, I’m not building it for anything particular, just to be able to do whatever I want and have fun.”
This truck, technically, is a 2006 GMC Sierra 1500. Visually, it is a Cat Eye Chevy with wide pre-runner fiberglass, big tires, and the kind of stance that makes you assume there is more going on underneath. Josh preferred the Cat Eye front end, and the aftermarket fiberglass options were simply better than what was available for the GMC nose.
Not much of what you see now was original to the project.
Somebody sent Josh photos of it about eight weeks before LS Fest West. The price was cheap enough to be dangerous, somewhere around $1,500, and the original plan was simple: throw in a junkyard 6.0-liter, drag it to Vegas, and beat on it.
“I was just going to throw the motor in it and just bring it here and just thrash on it, not care,” Josh said. “And then my OCD just doesn’t let me have a beater.”
So, the beater became a six-week thrash from bare frame. Josh swapped the cab for a white junkyard cab, pressure-washed and painted the frame, replaced hardware as it came apart, and turned what was left into a much cleaner truck than the timeline should have allowed. As he put it, the dash, interior, and chassis are about all that remain from where it started.
The engine followed the same path. Josh originally bought the parts for another crew cab project, but when that truck moved on, the parts were still sitting there. Instead of the junkyard 6.0-liter, the Sierra received a 408-cubic-inch stroker that Josh built himself, using Summit rotating assembly parts, AFR heads, Holley Hi-Ram intake, Holley injectors, a Holley accessory drive, MSD ignition, and a Nick Williams 102mm throttle body.
For now, it is naturally aspirated, but the truck is already being set up with boost in mind. Josh considered a turbo, but a supercharger is probably where it will end up. “I think I’d rather go supercharger,” he said. “A little less complex, more torque.”
Behind the 408, is a 4L80E with a 3,800-stall converter, feeding a stock 4:10 rearend. The rear axle is helped along by a B&M differential cover with bearing support, which is exactly the kind of practical part that fits the truck’s whole vibe.
Snail Fab built an all-in-one catch can, coolant reservoir, and overflow tank. The truck is plumbed with AN lines from the tank to the heater core lines. It also runs a Tesla electric brake booster with a GMT900 master cylinder, an aluminum radiator that Josh says holds around 170 degrees, a Holley Terminator X Max ECU, and a Holley Pro Dash inside.

The suspension is still relatively simple, too. Up front are Viking coilovers, while the rear uses Suspension Engineering’s new coil-link setup with Viking coilovers. The wheels are 20x12 Fittipaldis with 325/35R-20 Atturo AZ850 tires. That tire choice is intentional. Josh’s F-100 wore tires expensive enough to make every burnout feel like a bad financial decision.
“If I want to do a burnout, I’m not so worried about tearing up a $600 tire,” Josh said.
