per cylinder, Aluminum block, supercharged and intercooled, at 6500 rpm and at 4000 rpm of torque. 6.8 L V10 The SOHC V10 is another variation of the Modular family created for use in large trucks. Bore and stroke size is , identical to the 5.4 L V8. Both 2-valve and 3-valve versions have been produced. The 6.8 L uses a split-pin crank with 72° firing intervals and a balance shaft gear driven by the left camshaft to quell vibrations inherent to a 90° bank angle V10 engine. The engine's firing order is 1-6-5-10-2-7-3-8-4-9. The 2-valve version was first introduced in 1997, with a 3-valve non-VCT (the use of VCT was precluded by the presence of the balance shaft, as the shaft needed to remain in phase with the crankshaft) version to following in 2005. Vehicles equipped with the 6.8 L V10 Modular engine include the following: 2-valve 3-valve Ford of Australia Ford Australia used 5.4 L Modular V8s in the Ford Falcon and previously on the Ford Fairlane sedan model ranges, as well as in its high performance Ford Performance Vehicles (FPV) division models, until mid-2010, when they were replaced by the 5.0L. The DOHC 5.4 L V8s are named Boss by Ford Australia. The 3 valve SOHC V8s in non-FPV vehicles are named "Barra" by Ford Australia. Ford of Australia 4-valve DOHC 5.4 L V8 engines include: 5.0 L and 5.3 L Cammer In 2005, Ford Racing Performance Parts introduced a V8 crate engine for use in motor racing and home-made performance cars, officially called M-6007-T50EA, but more widely known as "Cammer". Since then, other higher performance variations of the Cammer have been introduced for KONI Sports Car Challenge and GT4 European Cup. All versions of the Cammer are DOHC 4-valve per cylinder designs with a bore and stroke of . The Cammer achieves its larger bore by resleeving the 4.6 L aluminum block. The T50 Cammer crate engine, the least expensive and most street oriented version, uses derivatives of the cylinder heads, variable runner-length magnesium intake manifold, and camshafts first used in the 2000 FR500 Mustang concept car. These parts are unique to the T50 Cammer crate engine and are not found in any other production Modular applications. The T50 has an 11.0:1 compression ratio and exceeds with the proper exhaust manifolds. The Cammer that has seen success in Grand Am Cup powering the Mustang FR500C is officially
