Future Shelby GT350 and GT350R Mustang owners will have plenty of firepower for the strip and track, thanks to Ford’s new 5.2-liter naturally aspirated V8.

The new flat-plane crankshaft engine generates 526 horsepower and 429 lb-ft of torque, delivering 102 horses per liter of displacement. Redlining occurs at 8,250 rpm, making the V8 the highest-revving unit used by any of Ford’s lineup, while 90 percent of its peak torque occurs between 3,450 rpm and 7,000 rpm.

The power generated by the 5.2-liter will be funnelled to the back via a Tremec TR-3160 six-speed manual, the only transmission available aboard the Shelby GT350 and GT350R. The six-speed uses a die-cast aluminum case and clutch housing for increased stiffness, and the dual-mass flywheel and dual-clutch disc were both optimized to reduce inertia and weight.

The engine itself is based on an aluminum engine block whose cylinder walls use Ford’s patented plasma transferred wire arc cylinder-liner technology, replacing iron cylinder liners with an electroplate coating. Further weight savings include a gun-drilled flat-plane forged-steel crankshaft, and a high-capacity composite oil pan whose baffling can handle sustained high-speed cornering and hard braking situations.

I wish they'd drop it into more of their cars. Say, does Ford still make the Modular?

  This is technically a Mod motor. Any V8 or V10 they have is part of the Modular family.

last gasp of the 'large' displacement naturally aspirated V8s?

Wjtinfwb Hmmm. Given that most Ford designs are doing relatively well in the marketplace, if this was forced I'd bet it was over the S650 Mustang. It's not a bad looking car but some angles seem very derivative of other makes, never a good trait for a car as distinctive as Mustang. And if he had anything to do with the abysmal dashboard, that's reason enough. Mustang doesn't need the "Tokyo by Night" dash arrangement of a more boring car. Analog gauges, a screen big enough for GPS, not Netflix and some decent quality plastics is plenty. The current set-up would be enough to dissuade me from considering a new Mustang.
Lorenzo Aw, they don't need a designer - just put modern underpinnings on a 1955 Ford Fairlane. Stellantis could revive Chrysler and Dodge by putting modern mechanicals on a 1955 Imperial and 1955 Dodge Coronet.
Lorenzo For both models, and their larger Accord/Camry models, the crash test ratings are very close, but only for late year models. The pre-2010 Civic and Corolla both fold like a cheap suit in a crash. If you're looking for a safer 10 year old vehicle, buy a truck.
