The 392 raised-deck engine released in 1957 had a bore and stroke. The actual displacement is . The deck height, at , was taller than that of the previous blocks. Because its deck was taller, the heads were cast with wider intake ports so that earlier manifolds could be used with the new heads on the new taller block. For 1958, Chrysler offered the 392 in two configurations: with 9.25:1 compression and with 10:1 compression, both with a single four-barrel carburetor. A dual four-barrel version of the 392 available in the 1957-58 Chrysler 300C & 300D cars was rated at ; the 300D, and some marine and industrial engines, used a (now rare) adjustable rocker. An extremely rare option available on the 1958 300D was Bendix "Electrojector" fuel injection, with which the 392 was rated at . Due to reliability problems with the primitive onboard computer which controlled the injection system, however, 15 of the 16 300D cars built with the fuel injection option were recalled and retrofitted with carburetors.
