[QUOTE="Trickymissfit, post: 532421, member: 25383"] auto manufacturers and the grand idea of designing and building a deisel engine is a joke! Navstar did the 7.3, and it was a pretty good engine. Not great on emissions and fuel milage but by the time they were into their third year of production they still had a great powerpack (stick shift). They had a lot of problems with the fuel delivery system at first because Ford wanted some cheapo fuel injection system (note: Navstar was against this from the start). Ford also did away with the sodium filled valves and paid dearly for it. Dodge just went to Cummins and said "build me a motor", and we'll pay the bills. G.M. wasn't any better than Ford, and it cost them several billion to get the Duramax working right. There are at least three half ton deisels in development right now. One is from Cummins and the rest are kinda shakey. Cummins has no less than three engine projects going on at the sametime for half tons, and one of them is rumored to be in a Jap truck (we'll see). CAT has a six that is turning a lot of heads right now, but needs about 25% better fuel milage. The goal is 25 mpg with 460 ft. lb. of usable torque gary [/QUOTE]
