With all the talk of supercharged 5.2L Voodoo motors regarding the (yet-unconfirmed) future Shelby GT500 Mustang, we’d gotten rather cozy with the thought that that’s exactly the motor the new super-‘Stang would get.
But now, a new rumor has surfaced: that the forthcoming Shelby GT500 will be powered by a brand-new, normally-aspirated V8 displacing 7.0 liters. However, be sure to take the news with a grain of salt, as it comes from a site we’ve never heard of called “SpeedTwitch,” which has made some other dubious claims in the recent past – e.g. that the 2019 F-150 Raptor will be powered by the same 7.0L V8, and that the 2017 Ford GT would have “the best power-to-weight-ratio [sic] of any car, ever” with 630 horsepower and a 2,890 curb weight.
Not only are both figures inaccurate, but there are quite a few cars with better power-to-weight ratios (Porsche 918, Ferrari LaFerrari, etc.).
Yet, to SpeedTwitch‘s credit, Ford is indeed reportedly planning to announce a new 7.0-liter V8 to replace its aging 6.8-liter V10 (according to Automotive News). We have our doubts as to whether such a mammoth truck engine could be made to fit neatly into the S550 Mustang, but SpeedTwitch claims an insider told the outlet: “Ford’s new 7.0L V8 variant will be built in Canada, and the short blocks for the motor will be sent to [Ford Performance Technical Center] in Concord for the addition of ‘go-fast’ parts.” The insider also reportedly said the Shelby GT500’s V8 “will feature direct injection, and some seriously high-flowing heads and upper intake assembly.”
We won’t hold our breath.
