Diesel Brad Posted June 11, 2006 Share Posted June 11, 2006 Im a newbie here, just bought a 1960 B61 (it has a later 237 hp in it)and few days ago I was fueling up at a stop when I heard a awesome sound, turned out to be a Mack that pulled next to me. He popped the hood, and it was a V8 ! Can anyone tell me a little history & specs on this engine. It sounded as good as a old Detroit !

Diesel Brad Posted June 12, 2006 Author Share Posted June 12, 2006 Im thinking emissions were a contributor to Mack dropping it. I know Cummins made a 903 cid diesel and it had valve issues.

ThaddeusW Posted July 9, 2010 Share Posted July 9, 2010 Im thinking emissions were a contributor to Mack dropping it. I know Cummins made a 903 cid diesel and it had valve issues.Yup, Emission laws were a big issure for Mack. Even in the early 90's they were having trouble meeting them. In reality I believe the E9 could have met 1998 and 2002 and 2004 regulations. They would have had to switche to electronic injection and EGR. However, they would have had to redesign for 2007 and 2010.Edit: For some reason I replied to a 4 year old topic Quote -Thad What America needs is less bull and more Bulldog!
