SRT-4 vs. Plymouth Belvedere

A mildly modified 2004 Dodge SRT-4 takes on a four-speed, 383-powered 1965 Plymouth Belvedere in a street matchup that should have favored the turbocharged compact. More than a decade of comments still argue over who really won, split between Mopar loyalists and turbo-four believers. Watch to see whether raw displacement or forced induction wins the day.

A turbocharged economy car and a fifty-year-old family sedan lined up at the same starting line, and on paper it should not have been close. The 2004 Dodge SRT-4 was built to embarrass far more expensive sports cars with its factory turbo four-cylinder, while the 1965 Plymouth Belvedere across the line carried nothing more exotic than a 383 big block and a four-speed manual, technology decades older than the SRT-4’s own platform. Modest mods on the little turbo car should have made this a formality. Instead, the video’s comment section is still arguing, more than a decade later, about who actually deserved to win.

What a Mildly Modded SRT-4 Brings to the Table

The 2004 Dodge SRT-4 came from the factory with a turbocharged 2.4-liter four making 230 horsepower and 250 lb-ft, up fifteen horses on the 2003 launch car thanks to bigger injectors and a fresh ECU calibration, a genuinely quick number for a compact in 2004, and this particular car carries only modest modifications on top of that baseline rather than a full built-motor setup. That combination made it one of the fastest cheap cars sold in America at the time, capable of beating far pricier metal in a stoplight race, which is exactly why lining it up against a forty-year-old Mopar felt, at least on paper, like an unfair fight in the SRT-4’s favor.

The 383 Big Block Doesn’t Care About Your Turbo

Under the Belvedere’s hood sits a 383-cubic-inch B-series V8, a workhorse Mopar big block that powered everything from family sedans to genuine muscle cars throughout the 1960s, here backed by a four-speed manual transmission that puts the shifting entirely in the driver’s hands. Commenters who watched this race repeatedly point to that four-speed as the difference-maker, noting the driver rowing through gears like a pro while the turbo car waits on boost to build. There’s no substitute for a big-inch V8 making usable torque from idle, and this Belvedere proves the old cliche still holds up on a real street.

Why Turbo Lag Still Matters in a Street Race

A factory turbo four like the SRT-4’s has to spool before it makes its peak power, a small but real delay compared to a big-block V8 that makes strong torque the instant the throttle opens. In a rolling street race with an unpredictable start, that lag can cost a turbo car the crucial first hundred feet, exactly the window where the Belvedere’s driver seems to get his advantage in this footage. It’s the same reason drag racers have spent decades building anti-lag systems and two-step launch control for turbocharged cars, since the technology has always needed a workaround that a big block simply doesn’t.

A Plain-Looking Family Car With a Muscle Car Heart

The 1965 Belvedere wasn’t Plymouth’s flagship performance model, that distinction belonged to the Satellite and, later, the GTX, which makes a well-built 383 example like this one something of a sleeper even by muscle car standards. Plymouth offered the 383 across multiple Belvedere trims as a mid-tier option, meaning this car could plausibly have started life as a fairly ordinary family sedan before somebody decided a four-speed and some engine work were worth the investment. The 1965 model year also marked a full redesign of the B-body platform underneath the Belvedere, the same architecture that would go on to underpin the Charger, Coronet, and Road Runner in the years that followed, meaning this unassuming sedan shares its bones with some of Mopar’s most famous muscle cars.

The Comment Section Still Can’t Let It Go

More than a decade after this video was uploaded, new comments keep arriving from viewers taking sides, Mopar loyalists insisting there’s no replacement for displacement, and SRT-4 owners arguing a well-built turbo car in the right hands should never lose this matchup. The channel’s own upload note admits they have no idea who either driver actually is, just that both cars looked good enough to be worth filming, which has only fueled more debate rather than settling it.

Two Eras of Mopar Performance, Side by Side

Whatever the actual result, the pairing itself tells a story about how Chrysler’s performance philosophy changed across four decades, from big, simple displacement doing the work in 1965 to a small, complicated, boosted engine squeezing big numbers out of a compact platform by 2004. Both approaches trace back to the same corporate DNA, just separated by the fuel crises, emissions regulations, and turbocharger technology that reshaped what fast meant for Mopar between the Belvedere’s era and the Neon’s.

Why Sleeper Belvederes Still Turn Heads

Well-preserved four-speed 383 Belvederes have become increasingly sought after by collectors precisely because they were built in smaller numbers than the flashier GTX and Satellite models wearing similar drivetrains, and clean survivors rarely come cheap when they surface at auction today. A car like the one in this footage, still being driven hard on the street decades later rather than trailered to shows, represents exactly the kind of usage that keeps the muscle car hobby alive rather than turning every survivor into a static display piece.

What This Matchup Says About Judging Cars by Spec Sheets

On paper, horsepower and torque figures would have predicted an easy SRT-4 win, turbocharged engines routinely outperform their displacement class when tuned well, and 230 horsepower from 2.4 liters was genuinely impressive for a factory compact in 2004. But drag strips and street races don’t run on spec sheets; they run on gearing, launch technique, tire grip, and the driver’s ability to get power to the pavement without spinning the tires or bogging the turbo. That gap between paper performance and real-world results is exactly why videos like this one keep getting watched, since the outcome isn’t always the one the numbers suggest it should be.

The Neon Platform Underneath the SRT-4

Dodge built the SRT-4 on the humble Neon compact platform, a car normally associated with rental fleets and first-time buyers rather than genuine performance, which made the factory turbo package even more of a shock when it arrived for 2003. Squeezing 230 horsepower out of a front-wheel-drive economy car required careful attention to torque steer and traction, engineering challenges the 1965 Belvedere’s simple rear-wheel-drive, solid-axle layout never had to solve in the first place.
