Automan2164 Posted October 20, 2012 Share Posted October 20, 2012 It was brought in around '96 (?) when Chrysler was trying to refine the 4.0. It was part of an NVH program (Noise, Vibration, Harshness). Rob Link to comment Share on other sites More sharing options...

Rob As well the 1996 and up blocks have extra ribbing for better structural integrity. Which is why I am building my stroker based off one of those.

Dookie Posted October 20, 2012 Share Posted October 20, 2012 I've heard alot that the renix has a higher nickel content and is stronger. Not that I don't doubt the 96 could be better. Link to comment Share on other sites More sharing options...
