Brazilton KS | If the engine and truck are in good condition, you won't go wrong for your use. Fuel efficiency will kill them on the road, but @ 3000 miles per year that's hardly worth considering. An 8v71, 6v92, or 8v92 won't cost much to replace from a salvage yard, either. They are tough old engines....if you can get it started, it will run all day no matter how worn out it is. There used to be some TS14 scrapers around here which took most of a can of either per engine to get started, but they ran 'til the job was done, and probably the next one, and the next one, and... I remember some literature I had back in the late 80s which was talking about the things Jon mentioned. The page on generator applications had information on the lag between the time the generator was tiggered and when it came online @ full power. The lag of the 2 stroke DDA was something like 1/4th that of the nearest competition. When it cranks, it hits on every cylinder the first round and it's off, then it accellerates to synconous speed much faster then a 4 stroke. Plus, it has no restrictions on going to full load immediately at startup @ normal room temperatures. I guess it's useless information, but in a way it's similar to the life of a farm truck. Nothing smoother then an 8v71 @ 2350 rpm.... over 300 times per second a cylinder is hitting. An 855 @ 1900 hits less then 100 times per second. Well, maybe a 12v would be smoother.....someday I want a truck with a 12V71 or 92...that would take it up to almost 500 fires per second!
Yes, the 2 stroke DDA is said to be the most efficient device created to turn diesel fuel into noize, but it will 'haul the mail'

What can you tell me about da old detroit diesels?
