Chronology
Predecessor Talbot 14-45

The Talbot 105 was a high powered sports car developed by Talbot designer Georges Roesch. It was famously fast, described by one authority as the fastest four-seater ever to race at Brooklands. [1]

History

The 75 was derived from the earlier 14-45, named according to its fiscal and actual horsepower. [1] The six-cylinder engine displaced a volume of 1,666 cc [1] and was the basis for all Talbot engines until the Rootes takeover in 1935.

The engine was repeatedly bored out further, giving rise to a succession of performance improvements. Throughout these developments, the exterior dimensions of the original 14-45 engine block remained the same although the 18-70 had an updated block with equally spaced bores. The later 105 had a different block again.

The 1930 London Motor Show saw the debut of the 18-70 model, bore and stroke both being increased to give an engine capacity increased to 2,276 cc. [1] In this form the car was later called simply the Talbot 70 or 75. [1] Higher compression ratios and a bigger Zenith carburettor resulted in an increase in power and the birth of the 90. Talbot's AO90s were highly successful in GP racing, coming third only to Speed 6 Bentleys in the 1931 Brooklands 500.

An increase in the engine capacity, still without any change to the exterior dimensions of the engine block, yielded a cylinder displacement of 2,969 cc for the iconic Talbot 105 model. [1] In 1931 four 105s were tuned to provide a reported 119 bhp, at 4,800 rpm. [1] In "Brooklands trim" further tuning and in increased compression ratio of 10:1 gave rise to a claimed 125 bhp. [1]

The Talbot acquired its fame on the racing circuits, featuring prominently at Brooklands, in the north-eastern suburbs of Surrey. In 1932 Talbot pulled out of racing, but a major Talbot dealer named Warwick Wright successfully ran a team of three 105s that year, and other teams operated by dealers and enthusiasts continued to race the cars at least till 1938.

The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi" due to their hemispherical shaped combustion chambers. The corporation had been seeking a smaller and lighter replacement for its FirePower engines, in part because new styling dictates meant moving the engine forward in the chassis which negatively affected weight distribution.

The Austin Motor Company A-series is a British small straight-4 automobile engine. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with three main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder blocks are not interchangeable between versions intended for conventional end-on mounted gearboxes and the 'in-sump' transaxle used on British Motor Corporation/British Leyland front wheel drive models such as the Mini. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several Formula One-title winning engines. Although a "clean sheet" design, the A-series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.

It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
