Engine

B-Series: The B-series engine is Chrysler’s first official big-block engine. Released in 1958, they existed until 1978. Available in 350 cubic-inch and 361 cubic-inch variants at first, there were also 383 cubic-inch and 400 cubic-inch B-series engines. They shared most of their architecture with the RB-series, but with a shorter 3.375-inch stroke. Both the B and RB-series engines featured wedge-style combustion chambers.

Casting numbers for the small-block Mopar and big-block Mopar engine blocks can be found on the left (driver’s) side of the block, and will consist of seven numerals. These
numbers are different than the stamped eight-digit number found on the right side of the engine. That number is the last eight digits of the Vehicle Identification Number.     When identifying the block, you want the raised seven-digit number, not the stamped eight-digit number.
