Dave & Laura Linn’s Contagious 1955 Chevy Bel Air
By Shawn Brereton – Photography by the Author
We all feel a connection with cars. Every one of them has a story. It’s why we write about them, and it’s why you buy this fine publication. Some are tedious to write, especially ones that were bought and just sit in a garage like a piece of jewelry. They are wiped down every now and then and maybe make it to the local cruise-in or ice cream shop, racking up a whopping 50 miles a year. No matter how much they cost, those cars have no soul. Those are the hard ones to write.
Then there are cars like Dave and Laura Linn’s ’55 Chevrolet Bel Air two-door hardtop that virtually write themselves. Dave didn’t do all the work himself (he probably could have), but he had all the right friends to help build the car he wanted, so why not use them? The Chesapeake, Virginia, native is a tech survey civil engineer with the United States Army Corps of Engineers by trade. He purchased the Bel Air in 2010 from his chassis builder, Mike Balf of Mike Balf Race Cars (MBRC), who had received it in lieu of payment for backhalving a car. It wasn’t just some car Balf had sitting off to the side waiting for service, though. No, Dave had to pull it out of a farm field in Carrolton, Virginia.
To say the car was a basket case when he got it would be an understatement. Looking at the “before” pictures, you would think that is how it got its name—the Virus—but Tetanus would’ve been more appropriate. However, Dave had a vision that saw straight through the layers of rust to the ultimate purpose-built Pro Street car capable of holding four passengers. He didn’t care that the earth was reclaiming the floors; he wasn’t using them anyway.

All fabrication was done by Balf, Cody Carlton, Charlie Colburn, and Dave. At MBRC, the car was put on a chassis table at ride height and the floor was cut out from rocker to rocker. Knowing Dave’s power aspirations, Mike built it with “bulletproof” in mind. He started with a custom-designed, dual-framerail, mild-steel round-tube chassis and steel floors welded together—so the car is solid. The power hits the ground through an unequal link four-linked Fab9 rearend fitted with an aluminum Yukon center, Moser Wavetrac differential, and Moser 35-spline axles. QA1 adjustable coilovers cushion the ride, while Wilwood disc brakes (six-piston front, four-piston rear) get it stopped.
Custom exterior mods include a welded front end with passive heat vents in the hood and front fenders. Those ’08 Impala door handles were grafted in for a sleek look. Balf welded up the trunk and converted it into a hatchback decklid with a nicely integrated wing and a third brake light. To complete the Pro Stock look, wheelie bars and a removable parachute hang out back.
Bay City Classics did the extensive bodywork, with Santos Colon getting the car laser straight before Derek Frasier applied the PPG Ford J7 Magnetic Metallic paint to perfection. For a killer contrast, the trim work and wheels were powdercoated satin black at RayceWerx. By the way, the wheels are Mickey Thompson HR-1s—18×6 front and 18×16 rear, with 33x22x18 MT radials.
The thing that sets a Pro Street car apart from a drag car is the interior, and Dave didn’t skimp anywhere; it’s just as slick as the outside. Pro Car seats hug the four occupants. Other notable features setting it apart from a drag car include a B&M shifter, Dakota Digital VHX gauge cluster, Vintage Air, Nu Relic power windows, and a Kenwood stereo complete with backup and sideview cameras. Mike and Dave made the dash, interior panels, and console out of bead-rolled metal painted body color, with hydro-dipped carbon-fiber accents on the raised areas done by Kevin Shonkwiler and Ken Simmons. Mike designed the interior caging to create the feel of a ’62 Corvette in the rear seats, which wraps around to make armrests. The panels are fastened with 250 nutserts and countersunk screws to add to the mechanical feel of the car. Seriously, we wouldn’t be surprised if this thing turned into a cyborg out of the Terminator movies—it looks like liquid metal.

For the powerplant, Dave wanted things kept “subtle,” which really means he didn’t want something sticking through the hood. The engine is a work of art and far from subtle. It is an iron-block 408ci (6.0L) LY6 built by Grave Digger monster truck engine builder Richard Midgette at Midgette Motor Sports in Poplar Branch, North Carolina. It’s got all the goodies, like CNC’d 823 heads, a Lunati forged crank, Callies Rods, Ross Pistons, and a turbo cam spec’d by Steve Morris. That cam comes to life through twin 67mm Turbonetics hair dryers with 50mm JGS wastegates and 50mm TiAL blowoff valves feeding through custom V-banded aluminum charge side-piping, twin-split intercoolers, custom stainless steel headers, 3-inch exhaust, and Borla mufflers. With all that air, the FAST Big Mouth 102mm throttle body and Holley Hi-Ram intake are pushed to capacity when the boost kicks in. The combo made 824 hp to the wheels with Ed Hutchins of HiTech Tuning working the keyboard.
An Aeromotive 20-gallon fuel cell with an integrated pump feeds the beast fuel through 10AN black fuel lines run through the chassis tubing for a cleaner look. Engine and transmission management is via a Holley Dominator computer, while Dave used a Ron Francis Bare Bones Express Kit with Mil-Spec connectors to get through the firewall to hook it all up. Power transfers through a 4,000-stall PTC torque converter to a Jakes Stage 3 4L80 transmission. A scary sidenote: It had a D3 trans brake until it triggered going across a two-lane bridge in Daytona at 40 mph. Luckily, Dave didn’t hit anything after his 190-degree spin, but he probably had to change his shorts afterward.
So, you might be wondering how the ’55 got the name “The Virus.” Well, after nine years of thrashing on his dream car, Dave completed it in . . . you guessed it, 2020. It was all dolled up and ready to hit the circuit with nowhere to go. However, it didn’t stop Dave; he built it to enjoy, so he hit the road. That spin mentioned above happened during one of its first major appearances at the 2020 Daytona Turkey Rod Run, just two months past its completion. Though he trailers it to faraway shows, Dave has been driving the wheels off it with over 3,500 miles on the odometer and just took home a Top 25 at his first Tri-Five Nationals in Bowling Green, Kentucky. That is one virus we’re happy to see out amongst the crowds!
