I didn't want to hijack the Mopar engine size thread with this so I'll list all of the various displacements for early Hemis here. The Hemi was first introduced in the Chrysler in 1951, the Desoto in '52 and then the Dodge in '53. The lowly Plymouth never got a Hemi until the 426 street Hemi days of the 60s.

DeSoto:
276
291
330
341
345
Dodge:
241
270
315
325
Dodge truck:
Used various Hemis already listed as well as a 259 version unique to trucks
Many of these engines were also available in a Poly configuration, using the same block but with a different top end. The Poly was no slouch either as it used the same staggered valve arrangement as the Hemi, only accomplishing it with a single rocker shaft. It also had a domed combustion chamber. The hottest one of these was a dual quad 345 cid version used in DeSotos that was rated at an equal 345 HP.
