The initial Rover version of the engine had a displacement of 3,528 cc (215.3 cu in). The bore was 88.9 mm (3.50 in) and the stroke was 71.0 mm (2.80 in). It used a sand-cast block with pressed-in iron cylinder liners, and a new intake manifold with two HS6 type SU Carburettors. The Rover engine was heavier but stronger than the Buick engine, with a dry weight of about 170 kg (375 lb). It was first offered in the 1967 Rover P5B saloon, initially making 160 PS (118 kW; 158 hp) at 5,200 rpm and 210 lb·ft (280 N·m) of torque at 2,600 rpm on 10.5:1 compression (5-star petrol was then still available in the UK). With the introduction of the Rover SD1 in 1975, the engine was improved with the ‘rope’ oil seals for the crankshaft ends replaced with lip seals, spark plug dimensions changed and the compression ratio lowered to 9.35:1.
