    220 with 5x3od. Sweetest sounding cummins in my collection. Its run as long as i’ve been around without an overhaul. I think it was at least once back in 60’s. #5 uses a little oil. Probably only has around 600,000 total on it.Top geared at 48 mph at 2100 rpm with 54,000 gross of bulls. Wasn’t a highway star. I don’t know why but i’ve found the 5x3’s to be the orneriest of the twin sticks to drive.

    Eeh... sometimes. But as long a Cummins can be kept up there. The Cats however have a way of hanging in there.

    Regarding that old A/C that would be a trip down memory lane for me for a few minutes anyhow. Boss man used to keep me in them that he had in his time here in Arkansas for a little while. They are good trucks if you keep a eye on everything. No reason they wont do well today if everything is in order with them old iron. Fuel mileage would be your biggie.

    Do not let that engine rev past 1000 until your water and engine oil temperature (And pressure is adequate, the turbo don't like it when it's cold and revved too early in warm up.) and the same would go when your day is finished let her sit and idle 6 to 10 minutes and cool down before shutting off.

    Good luck with it.

    That's some really good advice, thanks so much. It does have the shut off timer which I guess is why they were put on those old trucks to allow it to cool down. On my 3406 b I always let it idle for 30 minutes to warm up, and never use my Jake's until water temp is 150°.

    30 minutes, Im not surprised. I would be in the drivers room getting paper logs and everything else together for the run while shes sitting there coughing and wheezing from the cold. After a certain point I hear music out of it, check the gauges and see if they match it. Then it's time to go. But not until that music.

    Once moving it might take another 20 minutes to get the arthritis out of everything else (Wheels etc) once you get warmed up axles and all then you can go ahead and apply the jacobs or full power.

    One other thing. Keep a little bit of that lidocane that we have today for your foot. I don't know if that truck is one of those where you have to stand on the hammer on the floor all day. Some of that iron was in my time. Not enough engine for the loads we put on them.

    If anything carry a bit of can gun grease and fluids for her. Keep a milk crate or something on the right pax floor with them all in it. She'll maybe mark the territory and what not. I suspect many new trucks are not paid attention to by younger drivers who just crank em over and drive off in a minute as if they were a car. Those new trucks don't last either. Not like this A/C would.

    Hopefully your roads are good. if you are a shake box either you are abusing it by speed or its not quite loaded right on your drives. (34000) And sometimes the dash might come loose. Not too often. I would not remember now whats what to fix that it would take alot of shaking. If you have airride back there then it's not so bad.

    I do have air ride, and she has been correctly stretched 48". I'm expecting it to ride out pretty smooth. The milk crate will go in my passenger side tall sleeper door just right. It has straight 5" stacks. There is a mount under the frame for a muffler. I will find out on my first trip if I will be putting a muffler on or not.

    I don't know where your hearing is today, but some trucks you had that turbo whine to tell you that shes doing well. (or not...) the muffler would sometimes be there or not. Im deaf so it really didnt bother me too much because she is usually loud enough for me.

    This being winter I think you will smoke constantly starting at about 15 degrees on down. puff puff puff...

    If there was anything that caused me trouble in those days it would be the old flapper on top of the exhaust. Sitting at a light waiting for green it clanged so much. Annoying.

    Now that's funny, I've not thought about them in a long time. I always hated parking beside someone with those exhaust caps flapping while I'm trying to sleep.. I've already named her "smokey", I think it will fit her.

    I’ve never personally heard the twin turbo’s on the cummins run so i can’t comment on the noise level. I know old timers that had them. One was originally in a ‘80 359. But by the time he sold it in 96-97 when I remember the truck the most it was a beefed up single turbo. He converted it to single cause of cost turbos weren't cheap back then either. I don't recall him saying anything about any performance difference. Unfortunately by the time he sold it he was done with life and tired.
