Over the last few months we’ve rolled out five individual segments (Part 1, 2, 3, 4, 5) on the buildup of Brian and Tyler Hard’s 1968 V4 Pro Modified Camaro that’s been constructed by the wizards at Tim McAmis Race Cars in Hawk Point, Missouri. The installments centered around the five different phases of race car construction, from the 25.1E chassis construction to engine and accessory fitment, wiring, interior assembly, and even the powder-coating process.
As Tim McAmis Race Cars is a one-stop shop for all things Pro Mod – along with just about every other race-car oriented accessory from composite body pieces to tools – it was up to the team to put the entire package together and deliver it to the Hard team at the end of the process.
Car owner Brian Hard is no stranger to the business world; as CEO and President of Penske Truck Leasing since 1988 as well as a member of the board of Directors of several large business entities, he has an idea about what it takes to bring together a successful program. He’s chosen McAmis to build a number of cars for the family’s racing operation – and the results have proven themselves out.
“Working with Tim and his team is an absolute pleasure. Whether it’s building a new car or updating an existing car, they always make you feel like your project is the most important project they are working on,” says Brian.
Left: TMRC uses a chassis surface table to construct the 25.1E chassis from the ground-up. This table has been precision-ground to .001-inch to ensure that the chassis is perfectly flat, which helps every aspect of the rest of the car's design. Right: The 25.1E chassis taking shape on the table. Each aspect of the car needs to be planned ahead of time.
From start to finish, the entire car has been constructed at TMRC, with the exception of components like the engine and transmission that were put together by their respective builders and shipped to the TMRC facility for installation.
According to McAmis, Hard Racing makes it easy for him to do his job. “They know exactly what they want as they’ve been through this process with us a couple of times in the past. I already know what they like in terms of options and complexity of the car. We base that all around having built the previous relationship up with the customers, how they race, and what they want,” he explains.
There are currently three cars in the Hard Racing stables, not including this one. It’s safe to say that racing is a way of life for this Pennsylvania family – when work is not front-and-center, you will likely find them at the racetrack searching for that extra edge in elapsed time.
“Tyler and I started running with a Super Stock Hemi ‘Cuda about seven years ago. Kevin McCurdy joined us about five years ago when we added our TMRC ’68 Camaro Top Sportsman car that Tyler has been driving up until now. A year after that, we added a blown TMRC ’68 Camaro Pro Mod that Kevin drives. With the addition of the new nitrous car, we’ll be running three TMRC ’68 Camaros along with the Super Stock ‘Cuda,” Brian explains.
As this is a nitrous machine that has the opportunity to race at significantly lighter weights at times, McAmis and the TMRC team have developed a titanium rear tail section that's attached to the main chassis with titanium fasteners through a double-sleeve arrangement. Titanium is also used in other strategic places throughout the chassis construction.
Chassis tunability is front-and-center in this build, as with all others that come out of the TMRC headquarters. Tim believes in building a stiff car that’s able to be worked by adjusting the suspension components to affect the vehicle’s performance.
Left: The use of adjustable upper strut mount cups is one of the hallmarks of a McAmis build. 'These will give us the ability to change the ride height of the front of the car while maintaining the correct amount of piston travel in the strut body,' McAmis explains. Left Middle: The entire body is constructed in-house in the Velocity Composites division of the company. Here's a precision-cut segment of carbon-fiber waiting to be turned into a V4 body section. Right Middle: The digital patterns are turned into body sections to be cut by the automated CNC cutting table. Right: A vacuum process is used to create the body sections in the mold. Vacuum compresses the carbon sections and squeezes the excess resin from the mold.

Here’s the finished body straight from the mold, after de-molding and trimming. The full body including front end, doors, and wing weighs just 53 pounds.
A build like this has a laundry list of details that need to be attended to throughout the process, as each particular component needs to be placed properly to avoid any sort of stack-up issues down the line. The Hard’s Camaro will use an 864 cubic-inch Buck Racing Engines-built 5.3-inch borespace big-block Chevrolet huffing a ton of nitrous oxide from Switzer Dynamics and exhausting through a set of Pro Fabrications’ finest headers. Transmission duties are handled by a Rossler TH210 Pro Mod transmission and Neal Chance torque converter.
Left: The big-block Chevy engine needs to be precisely fit within in the frame, and a fixture locates the engine and transmission on the chassis table. Middle: Double framerail construction is necessary in a car putting out this type of power to prevent chassis twist. Note the laser-cut tab for midplate mounting. Right: Safety is paramount during any Pro Mod build, and to that end the McAmis team uses only Racetech seats in all of their builds. Says McAmis, 'We feel this particular seat is the safest one on the market today. TMRC pioneered the use of these seats over eight years ago. They aren't cheap but at 250 MPH what would you be comfortable with?' Simpson safety equipment is used through the rest of the build.
The rearend of the car is one of TMRC’s billet designs, coupled with a pair of Mark Williams axles and Dewco differential. Rear suspension is handled by a TMRC 4-link riding on a set of Penske shocks, which will help to provide the ultimate in chassis tuning consistency. Weld Racing wheels and Hoosier tires round out the driveline.
Remember where we talked about weight savings? That theme continues through every single aspect of the car. The application of titanium is liberal throughout the build, in any place where it’s possible and accepted for use.
All of the carbon-fiber and titanium used in the build process helps to get the car down to weight, where it can be competitive with the blown combinations in Pro Mod.
Left: The throttle pedal mount and pedals are constructed from titanium. Right: Parachute handle mockup – the handle in the car as delivered is constructed from carbon-finer to continue the weight savings. The handle also makes use of an air release, which allows TMRC to tie in the Electrimotion Safety Shut Off Device.
One hallmark of a TMRC build is the level of fit and finish, designed to produce a beautiful car for the owner – that’s part of why as many components as possible are produced in-house, where Tim can keep an eye on construction techniques.
“The attention to detail is always first class with TMRC. From planning through final assembly it is always there,” Brian says.
Left: TMRC hides the body mounts by bonding them to the mounting tree, which permits a perfect exterior finish with no worry of imperfections bleeding through the paint. Middle: Aluminum rocker panels are constructed once the body is in place to provide the right amount of ground clearance and a clean profile that will cut through the air. Right: The titanium theme continues in the construction of the firewall, which saves approximately 12 pounds over traditional steel construction – and looks badass!
Test-fitting each and every component to the car is a necessity. McAmis says, “Once the body is mounted it is time to finalize some of the small accessory tabs and components that go inside of the car that just can’t be located until the body is solidly mounted on the chassis. This is also when we pre-fit all of the carbon fiber interior panels.”

Now that’s a powerplant! 864 cubic inches of Buck Racing Engines power topped with Braswell Split Dominators and lots of Switzer Dynamics nitrous solenoids.
Inside the car, the latest-and-greatest in race car electronics are used throughout, as data acquisition and computer tuning have become so prevalent throughout the industry.
To that end, an MSD Power Grid ignition system, Speedwire Systems wiring package, and Racepak dash and data recorder system have been installed.
When we chatted with Brian, he didn’t expect to have too many challenges, thanks to the excellent crew he’s assembled and the right-out-of-the-box readiness of the new car. Kevin McCurdy, Darren Miller, Jimmy Daniels, Nina Hard, Jan Hard, and Brian himself will all be onboard to get Tyler comfortable in the car and heading down the straight and narrow. There’s only one sponsor – Hard Racing, LLC.
“I suspect we’ll have the normal new car learning curve, and we hope to be competitive by mid-year,” Brian says. As competitive as Pro Mod has been in all its forms over the last year, we have no doubt Tyler will be right on the pace in no time.
