I was discussing my current major automotive build, Project Windstorm, with a friend. When I mentioned my plans to swap a Hellcat Redeye, one comment caught my ear. My younger friend referred to my Belvedere as a “sleeper” and it made me wonder if the term has become so loosely translated that it has lost its significant meaning in the automotive world of today.
Back in the musclecar era, certain vehicles appeared very mundane with factory steel wheels and dog dish hubcaps; they were plain Jane vehicles. But under the hood, the car packed quite a punch. One such vehicle that comes to mind is the Plymouth Road Runner. The Road Runner was basically a stripped-down Satellite, with trim and frills deleted; some times didn’t even have the dog dish hubcaps. They were meant for racing.
Those were factory ‘sleepers’ and it was well known that cars like the Road Runner, and the Nova SS were quite potent machines for the day. Back then, they were factory built sleepers, and most people who bought a car to build and race also added other cues that gave away the performance aspect. Whether it was larger tires, aftermarket wheels, or a hood scoop, we knew that the car wasn’t stock, and we knew it was fast.
But the 1960s wasn’t the first time we saw a factory sleeper. The 1949 Oldsmobile Rocket 88 was one such car, where the GM boys swapped the Rocket V8 from the 98 model into the much lighter 76 chassis. What looked like your basic economy sedan was one of the fastest cars of its time. They didn’t use the term ‘sleeper’ for these factory cars, that happened later in the 1960s and 1970s – but the concept was the same.
The Olds Rocket 88 could technically be called the first factory sleeper, but the term wasn’t really coined until the 1960s when GM, Ford, and Mopar played around with lightweight chassis and big engines. AI has it mostly right.
Since AI is all the rage, we thought we’d see what AI has to say about it. Some of the cars that AI claims were factory, or “natural” sleepers gave up the ghost, so to speak, by installing Magnum 500 wheels, used on Fords and Mopars, and Rally wheels on the GM versions. Still, for most musclecar guys, the factory musclecars weren’t really the same as what most of us deemed to be a bona fide sleeper.
Making a car look fast by adding performance-oriented bolt-ons removes the concept of being a sleeper. When Project Windstorm was first purchased, it was a driver, and was completely stock. It was fitted with 15-inch steel wheels, and there was nothing on the outside that gave away that we had built the engine to sport a 70% jump in power. But making it go faster, like at Willow Springs International Raceway, meant making it stop faster, and the need for larger, aftermarket wheels changed the entire aesthetics of the car.
The car was looking faster, handling better, and the looks almost demanded the performance to match. The Belvedere was no longer a sleeper, it was a weekend warrior that saw track time between trips to Palm Springs, San Diego, or even places like Leno’s Garage. We went to car shows all over town, and it was getting some notoriety being a magazine project car.
The sleeper concept was removed once we started changing the looks of the Belvedere. But even if the performance stays the same, the looks can change the perception that the car is stock. Even bolt-on items like Weld Racing wheels gives the car an expectation that it’s fast, even if it isn’t. Being a “sleeper” is also about the looks of the car.
However, growing up in the 1960s and being around musclecars for 50+ years is not make an automatic expert on what a sleeper is. For that, we turned to a couple people we respect in the industry, to get their input and see what they deem to be a sleeper, and what is not a sleeper. We watched them work on cars from the comforts of our living room.
The Experts Chime In: What Is A Sleeper?
Sam Memmolo – Shadetree Mechanic
Most of you will recognize Sam Memmolo as the guy from Shadetree Mechanic, Two Guys Garage with Dave Bowman, or Crank and Chrome. He also hosted a radio program called Sam’s Garage Radio Show. He is a 55+ year veteran in the automotive industry, and he’s worked on everything from fully restored classics to modern musclecars. He had also obtained ASE Master Auto Technician certification, which he used in his many years of hands-on experience.
His weekly shows appealed to the DIYers and professional mechanics alike, and he became a voice of knowledge for decades on his weekly TV shows. He has owned and operated two successful automotive service centers, sharing his expertise with us for decades. His reputation as a knowledgeable enthusiast with a desire to succeed certainly precedes him.
When we had reached out to Sam and sought his thoughts on the subject, he was game to share his expertise and offer some insight on what constitutes the sleeper. He said that he likes the factory sleepers, mentioning a couple that are among our favorites, as well. This is what Sam had to say to us about the coolest cars on the planet.
“Here is my opinion and I am sticking to it! A sleeper is a vehicle with an appearance very close to what it looked like when it rolled off the showroom floor.”
“A sleeper usually has drivetrain modifications, i.e. a modified and more powerful engine, better transmission and final drive, brakes and suspension upgrades that allow handling / stopping chores to accommodate more power. The idea of a sleeper is to have people think that the vehicle is box stock and surprise them with an exhibition of speed and power.
“Many factory sleepers have been produced over the years. One of my favorites was a Chevelle two-door sedan post car with coke-bottle hubcaps, no power accessories, vinyl seat covers and minimal trim. It sported a 327 ci small block with 365 horsepower and a 4-speed gearbox, as well as limited-slip rearend. It looked like something Grandma would drive to town, but was faster than most street legal contemporaries.”
“I don’t think today’s musclecars can be good sleepers. Things like the Mustang, Camaro, and Challenger are just that – musclecars. Today’s sleeper would be like a Hemi-powered Jeep Cherokee with a supercharger. These look like an average luxury SUV, but have great performance.
“Most of your front wheel drive cars have power limits due to CV axle configuration; there could be a sleeper in a Chrysler 300, for example. A 6.4L Hemi with a blower and suspension / brake mods makes an awesome sleeper, just like the Mercury Marauder did from the Mercury Marquis.”
Stacey David – GEARZ
We remember Stacey David from his many weekends in our living rooms showing us how to customize cars and build performance. We also remember him as the guy who beat up Ted Nugent’s Bronco, and jammed with him afterwards. Whether it was a car or truck, he’s been in the trenches building the kind of vehicles most of us could only dream about: from huge lifts on military trucks to wild builds with a matching Fender guitar, we loved them all.
He is another one of those guys that we made plans for on weekends. His car projects usually got into the insane category with huge lifts on a former military truck to crazy builds that had Fender guitars modeled after them. And who can forget the way he very nonchalantly pulled parts off of a car and then playfully tossed them at the cameraman, followed up by that memorable laugh that is unmistakably Stacey?
We asked what Stacey thought would make a good sleeper, and which were his favorites. We’ve worked with him on a few cooling projects, and look forward to many more. Most of his builds are over the top, but he’s no stranger to the sleeper concept. This is what Stacey had to say about the sleeper.
“The whole point of a sleeper car came from the world of street racing for money where guys would go to different neighborhoods to take on the local hero. The more ‘unfast’ they could make their car look, the more bets they could get and ultimately the more money they could make.”
While these cars might all be very close to showroom condition, there’s just something about each one of them that makes you think performance. As Stacey said, it’s about misdirection – and these cars are all about attention.
“There are a lot of ways to make something look ‘unfast’, such as make it ugly, make it look like a show car, make it look neglected, make it sound bad, etc. In my opinion, the idea of a true sleeper vehicle can be summed up in one word – MISDIRECTION. You have to build the car to look like something OTHER than what it really is.
“A fast car is made to look slow, a road course car is made to look like a drag racer, etc. This is why a car like a Mustang or Camaro doesn’t really make a good sleeper, because their whole history is based on them being a sporty performance car. People expect a Mustang or Camaro to be fast, so there’s no big surprise there. They may not expect it to be as fast as it is, but that makes it a Hot Rod, or Musclecar, not a sleeper.
“A sleeper doesn’t necessarily need to be ugly, they just need to be a vehicle that is not recognized as a performance car. One big mistake some people make is thinking the sleeper idea is based on a certain look, or style of car, so they try and build something that has the right look, and end up with a car that’s neither a sleeper or fast. Remember: the sleeper is an idea and/or a tactic designed to separate a fool from his money, and there are a lot of ways to do that.”
We spoke with a couple of guys who have been at it for a long time, and they have been in our living rooms for years telling us what’s cool, what’s not, and how to make it cooler. I call both of these guys friends, and respect their knowledge and opinions, as well as their expertise. We all have our own opinions, and that’s fine, because it ultimately boils down to what you like and love about a sleeper. However, I’m putting my bets on what these guys had to say. How about you?
