Answer 2

Once upon a time each manufacturer made it's own basic engine package in-house, a Buick was a Buick an Olds was an Olds etc. The same was true of Chrysler during this period, each line carried its own some what "unique" engine. While the all shared the Hemi-type combustion chamber, only the Chrysler's had truly high output versions of those engines. Later the 354 and 392 versions made their way into some blown fuel cars mainly because of their head design and they were relatively easy to get .
