high up in the vee. Other claims maintain the pistons are aluminium alloy pistons, the connecting rods steel, the block cast chrome-iron, and the heads a sand-cast high-tensile light alloy. The nose of the crankshaft carries a torsional vibration damper, a four or six-bladed fan, and the pulley for the triangulated thin belt drive for the dynamo and water pump. The dynamo is located between the cylinder blocks on the smaller 2.5. At the rear the drive is taken from the back of the camshaft for the distributor positioned high above the unit behind the two semi-downdraught SU carburettors. There is a separate exhaust system for each bank of cylinders. Light alloy is used for the valve covers, tappet blocks, sump and inlet manifolds. Cooling is by pump and fan with a thermostatic by-pass control.

Russ began to drive the car in 1974 taking over sole driving duties after Tony's retirement from the sport in 1976 due to a spinal injury. Russ continued the car's development all the way through its racing life. In 1980 it became the first drag car under 5.5 litres, and the first all-British car to complete a quarter-mile race in less than eight seconds. By the time of its retirement, the car, using mainly stock engine parts, produced 1400 bhp and ran the standing quarter mile in 7.2 seconds at 180 mph. The car was restored and was to be displayed at
Dunsfold Aerodrome near Guildford in April 2014.

However, the more likely explanation is that there was not the production capacity for the engine, and in any event the 4.2 litre mark X gave superior acceleration. All 4.5-litre V8 models sold were automatic, which makes connection to a manual transmission difficult.

800:, and the beginning of the 1963 season, Westbury built a new hillclimbing special called the Felday-Daimler powered by a 2.5-litre Daimler V8 with a 2 in (51 mm) SU carburettor and a Roots supercharger. Westbury won the 1963 RAC Hillclimb Championship in the Felday-Daimler, setting course records at Craigantlet in Ulster and Dyrham Park in Gloucestershire.

In 1970, Russ
Carpenter and Tony Anderson built the "Glacier Grenade," a rear-engined dragster. It was the first "All British" rear engined dragster of its type. Powered by a 2.5litre Daimler V8 it would compete in drag racing from March 1972 until 1989 when the car was outlawed from European racing.

The 90 degree V8 engine has a cast iron block, a short stiff dynamically balanced crankshaft carried on five bearings, light-alloy heads with part-hemispherical combustion chambers, and two push-rod operated overhead valves per cylinder operated by a single chain-driven camshaft positioned centrally

He was already one jump ahead and had decided the engine would have its valve gear operated by push rods rather than by overhead camshafts! By following this route the engine would be cheaper to manufacture and he could introduce motorcycle engine practice when designing the cylinder head, drawing

The 2.5-litre engine, only 30 inches (760 mm) in length and developing 140 bhp (100 kW) @ 5,800 rpm, gave better performance than Jaguar's own 2.4-litre DOHC in-line six, and after the 1960 merger the opportunity was taken to create an up-market
Daimler V8 version of the

Limited investment in tooling for the 2.5-litre engine led to limited production capacity, with a maximum weekly output of 140 engines, and the 4.5 litre was only ever made in small quantities. This prescribed maximum output was never achieved during the production of the engine.

Daimler V8 engine were too high and ordered its discontinuation. The Majestic Major was discontinued without replacement in 1968, followed by the V8-250 in 1969. By 1970 the Daimler range was reduced to the
