The SOHC version was introduced in 1997 in the Ford Explorer, alongside the original pushrod version. It features a variable length intake manifold and produces 210 hp (157 kW) and 254 lb·ft (344 N·m)f. It uses a jackshaft in place of a camshaft to drive a timing chain to each cylinder head. Three timing chains are used, one from the crank to the jackshaft, one in the front of the engine to drive the cam for the left bank, and one on the back of the engine to drive the cam for the right bank. Ford has since phased out the engine in favor of the more powerful and efficient Duratec 37.[4]
A version of the engine is used in the Land Rover LR3 in Australia and Canada, producing 216 hp (161 kW) and 250 lb·ft (339 N·m) of torque at 3,000 rpm. The Land Rover version of the engine became unavailable in the United States for the 2008 model year[WIKI]
