Quote: I did some research and found out its a poly engine. So did it come stock in a 55 ply
Yeah, the 55 Plymouth V-8 is actually a Dodge poly engine, probably a 259. Plymouth didn't get its own V-8 until 56.
The 55 Plymouth/Dodge poly can be converted to a hemi using Dodge hemi heads. Can't do that with the Plymouth V-8 (which eventually got used in Dodges, but is a completely different motor than the 1953-58 Dodge hemi/poly).
