Unleashing 8,250 RPM of Pure Shelby GT350 Bliss: The Ultimate Mustang Experience

A Voodoo flat-plane V8 that revs to 8,250 RPM, a Tremec six-speed built to match it, and one owner’s E85-tuned example — this Shelby GT350 review digs into what makes Ford’s naturally aspirated Mustang halo car different from every GT500 and Terminator Cobra it gets cross-shopped against. Watch to see if it lives up to years of anticipation.

A flat-plane-crank V8 revving to 8,250 RPM is not a spec sheet number — it’s an experience most Mustang owners will never have, because Ford built the engine behind it for one specific car and stopped. This reviewer had wanted to drive that car since it first appeared in 2015, and when a friend finally handed over the keys to his own Shelby GT350, the moment lived up to years of anticipation. What happens when the engine everyone talks about actually delivers on the hype?

The Voodoo Engine, Explained

The GT350’s 5.2-liter Voodoo V8 uses a flat-plane crankshaft, a design borrowed from European sports cars and Formula 1 rather than the cross-plane layout in every other domestic V8 Ford builds. That crank geometry is what lets the engine spin to a redline near 8,250 RPM and produce the high-pitched, almost exotic exhaust note that separates the GT350 from every other Mustang on the road. In this review, the host leans hard on the engine’s revviness, calling it one of the purest sports cars currently for sale — high praise for a car wearing a Ford badge, but a claim the flat-plane V8 backs up every time the tachometer sweeps past 6,000 RPM.

A Six-Speed Built to Match It

Ford didn’t stop at the engine. The GT350 pairs the Voodoo V8 with a Tremec six-speed manual, a gearbox chosen specifically to handle the engine’s high-revving nature and torque curve without feeling like an afterthought bolted to a special engine. The review calls out the transmission by name as part of what makes the car feel complete rather than assembled from parts-bin components, and that distinction matters for a car built in relatively low volume specifically to chase a driving experience rather than a horsepower number on a spec sheet.

The E85 Angle

This particular review is built around a GT350 running E85, a higher-ethanol fuel blend that allows for more aggressive tuning than pump gas typically supports. E85’s higher octane rating lets a tuned engine run more ignition timing or simply extract more naturally aspirated power through a richer, more aggressive tune, and Voodoo owners chasing extra output without forced induction often turn to E85 specifically for that reason. It’s a detail that separates this from a stock press-car review — this is an owner’s car, tuned and driven the way an enthusiast actually uses one.

What Owners Say About Living With One

Comments on this video from other GT350 owners back up the review’s enthusiasm, with several calling it one of the best overviews of the car they’ve seen. One owner mentions removing the factory hood prop rod in favor of hydraulic hood struts — a common early modification — while another notes their GT350 has never triggered the factory change-engine-oil-soon light, a small but telling detail about how these cars get driven versus how far people actually put on them. That kind of specific, lived-in feedback is different from generic praise, and it’s a signal the review resonated with people who actually own the car being discussed.

GT350 vs. GT500 vs. Terminator Cobra

Every high-performance Mustang generation invites the same debate, and the comments here are no exception. One viewer describes considering a GT350 before ultimately choosing a Terminator Cobra, calling the GT350 one damn sweet Mustang despite going a different direction. Others point to a specific market shift: as the supercharged GT500 became available, some GT350 owners traded up, and used GT350 prices softened as a result of that migration. It’s a useful reminder that the GT350’s naturally aspirated, high-revving character is a specific choice, not simply a stepping stone to the more powerful supercharged car — some buyers want exactly what the Voodoo engine offers and nothing else.

The Track Package Detail

For buyers cross-shopping model years, one comment flags a genuinely useful spec point: the 2016 GT350 offered a Track Package that added engine oil, transmission, and differential coolers — hardware aimed squarely at drivers who intended to actually track the car rather than just drive it hard on weekends. That’s the kind of option-code detail that matters enormously to a buyer trying to verify what a specific used GT350 actually came with, since the base car and the Track Package car cool very differently under sustained hard use.

Why This Review Still Gets Watched

Ford has since ended GT350 production, folding its performance halo duties into other trims, which makes reviews like this one — filmed with an actual owner’s car rather than a press fleet loaner — a small piece of a car that won’t be built new again. The flat-plane Voodoo V8 remains one of the most distinctive engines Ford has ever put in a Mustang, and reviews built around a real owner’s honest reaction to driving it hold up better than manufacturer-supplied test drives ever could.

What Came Next for the Voodoo Engine

Ford has since replaced the GT350 in its lineup with the supercharged GT500 and its Predator V8, meaning the naturally aspirated Voodoo engine featured in this review is no longer in production and won’t return in a future Mustang. That makes this specific driving experience — an engine that revs to 8,250 RPM without any forced induction at all — a genuinely finite thing, and it’s part of why owners quoted in the comments describe the GT350 as a car they’d recommend experiencing rather than simply reading about. A flat-plane V8 built purely for high-RPM character, with no turbo lag and no supercharger whine, isn’t something Ford is likely to build again anytime soon.

The GT350’s Racing Roots

The GT350 name itself dates back to Carroll Shelby’s original 1965 Mustang GT350, a homologation special built to make the Mustang competitive in SCCA road racing. Ford’s decision to revive the badge in 2015 for a car built around a bespoke flat-plane V8 rather than a warmed-over base engine was a deliberate signal that this wasn’t just a trim package — it was meant to earn the GT350 name the same way the original did, through genuine road-course capability rather than straight-line bragging rights alone. That heritage is part of why enthusiasts in the comments treat this car with a level of reverence that a badge-engineered special edition rarely gets.
