5.8 L
A 5.8L (5808 cc, 354 CID) DOHC 4-valve Modular V8, dubbed Trinity internally by Ford, is introduced with the 2013 Ford Shelby GT500. The 5.8 L's bore and stroke are 93.5 mm (3.68 in) and 105.8 mm (4.165 in) respectively. The Trinity is based on the 5.4L V8 used in the previous model year GT500, utilizing the same block casting but receiving a 3.3 mm (0.128 in) increase in bore diameter. The PTWA cylinder lining technology first used in the 2011-2012 GT500 5.4 is retained in the 5.8. The 5.8 L benefits from cylinder heads with improved coolant flow, Ford GT camshafts, piston-cooling oil jets similar to those found on the 5.0 Coyote, new 5-layer MLS head gaskets, a red line increased to 7000 rpm (from 6250 rpm), and a compression ratio increased to 9.0:1 (from 8.5:1). Boost is supplied by a 2.3L TVS supercharger. At the time of launch, the 5.8L will be the world's most powerful mass production V8 and will propel the 3,850 lb (1,750 kg) GT500 to a 202 MPH top speed, it will also remain gas-guzzler tax exempt.
