Falcon Ute, using a mix a North American- and Australian-sourced components. 2009 models were developed to over 425 horsepower. The Ford GT mid-engined super car combined a new aluminum block with Cobra R cylinder heads, using a special compact cam drive, a production-based steel crankshaft rebalanced for unique connecting rods, a belt-driven external oil pump, and Lysholm® supercharger. The Romeo Engine Plant Niche Assembly Line even attached each dry sump oil tank for testing, then shipped it strapped to the engine for vehicle installation. While the GT production ended in 2006, Ford Racing continues to offer performance components. For the 2007 model year, 5.4L 4V supercharged usage shifted to the Mustang Shelby Cobra GT500, with a cast iron Windsor truck-based block, Roots blower, and conventional oil pan. Horsepower has grown from 500, to 540 (2010 model with dual-knock sensors), 550 (2011 with plasma spray-bored linerless aluminum block), OTHER V8 ARCHITECTURES 3.4L DOHC 4V “SHO” ENGINE minimized water-jacket cross-sectional areas to increase the fluid Yahama® produced this all-aluminum V8 for 1996 Taurus SHO, as a velocity in the jackets, thereby increasing heat transfer. 2003-2006 replacement for the 3.0L/3.2L SHO V6.
