The A-Series Engine - Its First Sixty Years
by Graham Robson
1951 = A-Series 803cc engine manufacture started in Longbridge, at the re-equipped North Works for the Austin A30 with Zenith carburettor and soon after also fitted to the Morris Minor in 1952 (designed by Alec Issigonis at Cowley, Oxford) but with an SU carburettor this time as insisted by the Morris engineers !
1962 - 1970 = all A-Series 'S' type engines were produced at the Morris Engine Plant at Courthouse Green in north of Coventry = production of all 970, 1071 and 1275cc S engines as designed by Eddie Maher & John Cooper (& early Midget/Sprite 1275cc engines) and the short lived A-Series Diesel.
1963 = Mainstream A-series production moved from North Works to the underused Longbridge, East Works which was re-equipped tp build up to 12,000 engines and transmissions every week for the Mini and 1100 ranges with the ability to also make in-line engines for Midget, Sprite, Minor, A40, etc.
By 1966 = East Works was producing 848, 998, 1098cc to suit demand as required.
In 1968 = East Works also started producing the 1275 non 'S' versions of A-Series for mainstream mass production.
(All 'S' versions of 1275 engine continued manufacture at Morris Courthouse Green, Coventry until the end of production in 1970's)
