We’ve been waiting, and now we know: After initially saying the new Mustang Shelby GT350 would make “more than 520 horsepower,” Ford has finally revealed the official figure. The GT350’s 5.2-liter flat-plane-crankshaft V-8 makes 526 horsepower, along with 429 lb-ft of torque.
Ford says those figures mark the GT350’s V-8 as the most powerful naturally aspirated engine the company has ever offered in a street-legal car. This is also Ford’s highest-revving V-8 ever, with a redline of 8250 rpm. The torque peaks at 4750 rpm, with 90 percent available across a broad band from 3450 to 7000 rpm; the max horsepower arrives at a lofty 7500 rpm. And it sounds great doing so.
