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 J-2, commonly known as Rocketdyne J-2, was a liquid-fuel cryogenic rocket engine used on NASA's Saturn IB and Saturn V launch vehicles. Built in the United States by Rocketdyne, the J-2 burned cryogenic liquid hydrogen (LH 2) and liquid oxygen (LOX) propellants, with each engine producing 1,033.1 kN (232,250 lb f) of thrust in vacuum.

The J2, a road-going two-seater, was the commonest car in the range. Early models had cycle wings, which were replaced in 1933 by the full-length type typical of all sports MGs until the 1950s TF. The top speed of a standard car was 65 mph (105 km/h), [ 3 ] but a specially prepared one tested by The Autocar magazine reached 82 mph (132 km/h).
The beginning of the S-II came in December 1959 when a committee recommended the design and construction of a high-thrust, liquid hydrogen fueled engine. The contract for this engine was given to Rocketdyne and it would be later called the J-2. At the same time the S-II stage design began to take shape.
