Re: Cool article I just ran across about the GMC engines
Jolly, the new 4.3 V6 is an entirely new engine and not just the old smallblock with 2 cylinders lopped off. Do some research and you will find out that the new line up of 2014 GM trucks have as well a completely new generation of engines and the only thing these engines share with the previous engines is the displacement. It has definitely been time to retire the old 4.3 V6 since it's basic design is from an engine that was introduced nearly 60 years ago.
