5.4L 4V GT500 Iron Shortblock 1200 HP (2007-2010 GT500) Built By JDM Engineering
Looking to bullet proof your 2007-2010 Shelby GT500 5.4L 4V engine? Team JDM has you covered with this 1200 HP capable, fully built iron shortblock! The weak-link in the factory 5.4L engine is with out a doubt the OEM connecting rods. Team JDM uses Manley H beam 4340 forged rods with ARP 2000 hardware. These heavy duty rods are used to support the rotating assembly with a Ford Performance Cobra Jet crankshaft and Mahle pistons with a custom ring package. Speed Pro bearings allow the crank and rods to spin freely with minimal friction limiting wear and tear. The oil pump is also upgraded to an O-ringed GT500 unit optional with billet gears inside for extra strength. If you are looking for a durable and reliable engine for your Shelby this is it! Most of the components used in this application Team JDM has tested and developed on their Cobra Jet Mustang race cars! JDM Engineering has a 1 year no-detonation warranty on all in-house built engines. Shoot us a call, and let us explain why we are the best in the industry for your GT500 engine build!
