by contrast chevy built the 100th million small block in 2011. yes, there were many many changes over the year, but still a successful engine. I'll bet ford has built similar number of their small block.
Now I have owned two duramax's. a 2004.5 that our son now has and is still running strong, but only has 160K miles on it. and a 2015 Denali.
both have been very nice trucks with zip issues.
but I'll bet cummin's has built more than 2 million of the engines used in the dodge and many motor homes along with many other applications.
