Dodge used the 426 hemi in Challenger, Coronet, Dart SS, and Super Bees between 1966 and 1971 and Plymouth dropped it under the hoods of a handful of cars in that same span, including the Barracuda, Belvedere, Fury GT, Road Runner, and GTX. A third generation hemi came along in 2003 with a displacement as large as 392 cubic inches, but the fact that it shares its block design with the LA series lands it in the grey area between big and small block engines.
The 440 cubic inch RB series motor, an undeniable big block at as much as 700 pounds with cast iron intake and exhaust manifolds, stayed in production until 1978. Smaller versions of the RB big block were also kept alive through that point, including the popular 383 and 400 cubic inch forms. By then, cast crankshafts had replaced the earlier forged versions, although Mopar’s big block engines remained carbureted long after many competitors had switched to fuel injection.
