The J-2 engine also had a slightly thinner head gasket, raising compression to 10.0:1. It was advertised with gross power and torque ratings of 312 hp (233 kW) at 4600 rpm and 415 lb⋅ft (563 N⋅m) at 2800 rpm. Oldsmobile charged $83 for the J-2 option with the three-speed manual (or in the 98), [7] $314 with the automatic. [8]

The MG J-type is a sports car that was produced by MG from 1932 to 1934. This 2-door sports car used an updated version of the overhead camshaft, crossflow engine, used in the 1928 Morris Minor and Wolseley 10 and previously fitted in the MG M-type Midget of 1929 to 1932, driving the rear wheels through a four-speed non-synchromesh gearbox.
M-Type Drophead Coupé 1948. The Allard Motor Company was founded in 1945, setting up in Clapham High Street, London. [4] Using its inventory of easy-to-service Ford mechanicals built up during World War II and bodywork of Allard's own design, three post-war models were introduced with a newly designed steel chassis and lightweight body shells: the J, a competition sports car; the K, a ...
