Talk:Chevrolet 153 4-cylinder engine

Derivatives
I am taking exception to the following quote from this article:

"The 153 engine is entirely different from the later Pontiac 151-cubic-inch (2.5 L) Iron Duke, but the two are often confused today."

Please see the discussion: http://en.wikipedia.org/wiki/Talk:GM_Iron_Duke_engine#Derviation
