wedge 340 vs non wedge 340

Not really.. It's just that the person who wrote that article/answer has absolutely no idea of what he speaks.

"Popular Applications


The Mopar 340 Wedge engine was first labeled on the E-body Plymouth Duster. It could be identified by a badge that read "Wedge 340" instead of "340 V-8." The designation confused consumers at the time due to the relatively low-power of the engine and the small cubic centimeter displacement that the design featured."

(E-body Duster?)


"Wedge Controversy

The Wedge concept was slow to take off because of this misconception. However, Mopar followed the 340 Wedge with larger and more powerful engines such as the 413 Max Wedge and the 426 Wedge."

(413 & 426 Wedge came after the 340? LOL)

cubic centimeters???
