Something wicked this way comes.

The Chevrolet Monte Carlo. It’s arguably one of the most overlooked cars of the original muscle car era, but when your stablemate is the 1970 LS6 Chevelle – arguably the most fearsome car in that golden age of horsepower – it’s easy to understand why. Adrienne Peters didn’t overlook it, and as a result, she has the most wicked first-generation Monte we’ve ever seen.

It helps that Ms. Peters has a deep connection to Chevrolet. She’s the performance parts product, marketing and social media manager for GM, and as you can guess, her murdered-out 1970 Monte Carlo is packed with goodies. Under the hood is an old-school 454-cubic-inch (7.4-liter) LS6 V8 sourced from a 1970 Chevelle, which isn’t a bad way at all to start an epic muscle car build. It’s fitted with a variety of parts, and though we aren’t told how much power it makes, the 1970 LS6 Chevelle had 450 horsepower (336 kilowatts) straight from the factory. So yeah, it should be quite fast.

To use that power, the Monte has massive tires on the back that are 13.5 inches wide. The rear quarter panels had to be modified for them to fit, and with the high-profile tire sidewalls the car absolutely screams old-school muscle. The matte black finish makes it look positively mean, and that’s carried over to the inside with a big black dash that Peters fabricated from scratch. You won’t find creature comforts, or a big touchscreen, or even door panels for that matter. It’s straightforward and functional, and it’s decidedly badass.

Peters bought the Monte when she was in college, and she describes it as being sinister with a steampunk vibe. The slightly larger proportions compared to the Chevelle make the first-generation Monte Carlo really stand out in the custom world, and this menacing build certainly has us impressed.
