Rob Green’s 1970 Chevy C30 Wrecker

SOME guys chase trophies. Some guys chase horsepower. And then you’ve got folks like Rob Green, who chase an idea. His idea was simple: build something different—not just another show truck, and not just another bagged Chevy sitting pretty in the parking lot. He wanted something that made people stop, scratch their heads, and say, “Damn, I’ve never seen that before.” That idea turned into Dirty30, a slammed 1970 Chevy C30 wrecker that looks ready to tow your ride straight out of the past and into the spotlight.

Why a Wrecker?

Most builders choose pickups, Blazers, or SUVs because they’re familiar ground. You’ve seen C10s dropped on big billets, and you’ve seen squarebodies with turbo LS swaps. However, a wrecker is an uncommon sight. Rob liked the thought of taking something built to work and giving it new life. He wanted to show off the lines of a big-bodied C30 but twist it with custom metal, modern power, and a stance that makes people’s jaws drop. As Rob puts it, he wanted “something cool and different.” That’s exactly what Dirty30 is. It nods to the past, but everything about it screams custom.

Three and a Half Years in the Making

This wasn’t a weekend project. Rob spent three and a half years putting this truck together. He leaned on some of the best shops and builders out there, and he had spent more than $300k by the time it was finished. Every inch of this truck has been touched, cut, re-fabbed, or rethought. That’s the difference between a simple build and one that makes the pages of a magazine. Marco Salazar had a big hand in the fabrication. He skirted the wrecker box so it lined up perfectly with the cab, raised the bed floor for clearance, and cut a custom firewall and trans tunnel to squeeze in the LT4 and 10-speed. None of that’s easy work. It’s the kind of cutting, welding, and grinding that separates dreamers from doers.

Heart of the Dirty30

Let’s talk about muscle. Under the hood sits a brand-new crate LT4—the 6.2-liter monster out of the ZR1. That’s 650 horses worth of “tow your butt” power. It’s wired with a Speartech harness, breathing through Speed Engineering headers, and dressed with custom Wegner Automotive valve covers. ZaccardiBuilt Garage dialed it all in, and even had to fit a custom oil pan to clear the Porterbuilt frame. Backing it is a 10L90 automatic—the same gearbox out of late-model performance cars. It shifts smoothly but can take a beating, which is exactly what a heavy hauler like this needs. Cooling comes from a Derale dual fan setup, and the two-piece driveshaft came from Rip’s Performance. This isn’t a “look at me” swap; it’s a full modern drivetrain that can tow, pull, and still put down rubber if Rob feels like it.

Frame and Suspension Done Right

A stock C30 frame wouldn’t cut it, so Porterbuilt built a new one, stretched and tailored for the wrecker body and push bumper. Slam Specialties air bags paired with Ridetech shocks and AccuAir air management keep everything riding smooth and laying flat when parked. Watching this wrecker drop to the pavement is a sight. It lays pinch welds, sitting so low you’d think it was welded to the ground.

The brakes had to keep up with the power and weight, so Wilwood components were the answer. With stainless lines, custom brackets, and the right balance front and rear, this truck stops as good as it goes.

Style and Attitude

On the outside, Dirty30 wears a two-tone blue and white paint job laid down by Marco Salazar and Jeff Behnke. It’s clean, simple, and fits the work truck vibe. But it’s the details that set it off. Pinstriping by the legendary El Bugs in Arizona, powdercoat from Matador, and Alcoa wheels from Lowboy Motorsports are tucked up under the fenders. The Boyd Welding fuel tank and custom touches throughout mean no corner was skipped. And yeah, it still looks like a wrecker. The lights, the boom, and the work-ready stance are all there, although the slammed altitude and modern touches make it feel more like a hot rod disguised as a tow rig.

Inside the Cab

The cab sticks to the theme: functional, but not plain. A Snowden bench seat wrapped in black by Jackson’s Upholstery gives it old-school charm with fresh comfort. Dakota Digital VHX gauges handle the readouts, while a custom sound system keeps the miles from feeling long. It’s not flashy, but it’s right. Rob kept it practical, the way a truck like this should be.

Built to Drive, Not Just to Show

Dirty30 has already earned its stripes at events. It hit SEMA in 2024, Dino’s Git Down that same year, and was slated for LST and even Moab in 2025. That proves Dirty30 isn’t just a garage queen polished for one weekend. Rob drives it. He shows it. And he’s proud to let people walk up, look under, and realize how much thought went into every nut and bolt.

Lessons From the Build

Every project has its headaches. Rob says the easiest part was driving it once it was finally together. The hard part? Writing checks and waiting for parts. He jokes that he’ll keep a closer eye on the checkbook next time, but that’s the price of chasing something unique.

If he had to give advice to someone starting their own build, he would keep it simple: let your imagination go wild. Don’t be afraid to try something out of the box. If he’d stuck to a safe build, Dirty30 wouldn’t exist.

Happy Ending

Dirty30 is more than a slammed wrecker. It’s proof that old iron can be reborn into something wild with enough vision, grit, and money. Rob Green didn’t build this to blend in. He built it to stand out, and it does exactly that. From the LT4 under the hood to the Porterbuilt frame under the cab, every piece of this truck tells the same story—that this is custom work at its finest.

So next time you see a plain service truck roll by, think twice. With the right builder and the right vision, even a workhorse can turn into a show-stopping, head-turning machine. Just ask Rob Green about his Dirty30.
