Leyland PE166 engine

The engine was loosely based on the older Triumph I6 (which it was intended to replace), and was initially intended to share some internal components with that and the Dolomite Sprint engines. However, during development not a single component remained unchanged, the last link being severed when the conrod big-end was increased in diameter over the Dolomite Sprint equivalent. Both the capacity variants use an bore, with a or stroke giving capacity respectively. The 2350 cc engine produces a maximum power of at 5000 rpm and a maximum torque of at 3500 rpm. The 2.6 L engine, meanwhile, produces a maximum power of at 5000 rpm and a maximum torque of at 3750 rpm. ==Background==

Following Leyland Motors' acquisition of both Standard-Triumph and the Rover Company in 1960 and 1967 (and the subsequent merger with the British Motor Corporation to create British Leyland a year later), a unified model policy was developed, with Rover and Triumph reorganized into the Specialist Division. Proposals were developed for replacing both the Triumph 2000 and the Rover P6 with a single product, codenamed SD1 (Specialist Division 1). ==References==
