The cummins went 24 valve in model year 1998.5
Cummins is good. Dodge is not. Cummins has always been a good engine. Dodge is lucky to have the contract with Cummins. I have 2 Dodge Cummins (an 1992 and 2006). Both have electrical problems and the transmission in my 2006 isn't great and that's with stock power and only 93,000 miles. The 12-valve Cummins is all mechanical- easy and cheap to get power out of it. The 24-valve Cummins is computerized- have to buy a programmer. The best combination would be a Cummins in a Chevy.
