Many makes utilized the wedge shaped combustion chamber. Chrysler used it as a marketing tool. Look at the area above the piston in the picture above. Between the piston top, valve, head and plug you can plainly see the wedge shape that squeezes the air fuel mixture toward the spark plug during compression, making for a more complete burn. Chevys were wedges from 55 all the way into the 2000s and most still are. GM just never used it as a marketing tool. Most automotive marketing names were just that. Marketing. But in this case when you see "340 WEDGE" callouts on a Duster hood for example, although it is marketing, it really meant something too.
