hen it comes to rebuilding a classic Chevrolet, there are certain models that pose more of a challenge than others; parts availability can play a huge role in the difficulty of a restoration. If you’re working on a first-generation Camaro, nearly every component is reproduced at large scale. Things get a little tricky for early Chevelles and Novas, but the king of difficult restorations is the Monte Carlo, at least in the muscle car era. Brent Davidson and his two sons, Andrew and Austin, can attest to that, as they recently finished the restoration of this ’71 Monte Carlo.
Brent always liked the styling of the first-generation Monte Carlo; these cars are known for their comfortable ride, so he took on the project back in 2005. It was a 350 car from the factory, but Brent had his heart set on a big-block from the moment the project started. The car was driveable when he bought it, but it needed a lot of work, cosmetically and mechanically. He paid $3,000 for the car and celebrated with a one-wheel-peel burnout before tearing it down for restoration.
Under the long hood is a Chevrolet Performance 502ci big-block crate engine. It was part of a Connect and Cruise package, making for an easy install. The big-block features a forged rotating assembly with a street-friendly 9.6:1 compression ratio. GM aluminum heads are paired up with a hydraulic roller camshaft to offer plenty of low-end torque. Instead of scrounging at swap meets for pulleys and brackets for the engine accessories Brent simplified the accessory drive with a CVF Racing Wraptor serpentine system, complete with compact A/C compressor, one-wire alternator, and updated power steering pump. The big-block is cooled by a Summit Racing aluminum radiator, which features dual electric fans. Brent outfitted the big-block with Hooker ceramic-coated long-tube headers, while Jimmy’s Pro Muffler & Brakes (Dayton, Tennessee) fabricated the 21/2-inch exhaust system with Flowmaster mufflers.
Cosmetically, the car was in rough shape when Brent brought it home, and it wore gold paint with a black vinyl top, a sure sign of underlying rust issues. It only got worse as they continued to dig into the body. The car got a new full roof panel, quarter-panels, and front floorpans to eliminate the rust, which is extremely common on these cars. Casey Runyon handled the bodywork, while local Chevy restorer, NuNu Lowry laid down the Sikkens paint, which has been sanded, buffed, and polished to a beautiful finish. New glass and trim were next on the to-do list, yet another challenging aspect of this rebuild.

Although Brent’s progress was slow in the early years, the involvement of his sons brought the project to life and eventually put it on the road in 2021. With such a huge investment of time and money, Brent’s Monte Carlo displays the talents of his sons, as well as local car guys in the area who contributed to the challenging restoration. Now that it’s on the road, it’s time to work out the bugs and enjoy the tire-roasting big-block, A/C, and overdrive, a modern take on classic Chevrolet luxury.
