    how good are older cummins big cam engines?

    Im looking at a 85 359 pete with a big cam cummins engine,just wondering how good these engines are and how well it will hold up. I run flatbed running mostly steel. I don't run very far out.only usually run about 2200-2500 miles a week

    They were pretty good engines in their day and will probably be ok for what you're doing with it.
    It will get pretty bad fuel mileage by todays standards.

    Mine will get around 6mpg most of the time, not bad for a 30+ year old engine, not sure what qualifies as bad mileage these days. Really just depends on how well the engine is tuned.

    Look into how recently the bottom end last had work done, if there is one bad thing about them it's that they will spin main bearings due to the design of the main cap. If they haven't been checked in the last 250K I would plan on having a little work done to it.

    Big cams were second in production numbers to only the mechanical 3406 in the day, parts are cheap and easy to come by.

    Hope that helps.

    Just what they said , reliable.Decent performance relative to their age but they have been known to spin the mains especially if you idle a lot.

    Parts are relatively cheap due to the long run of production and should be easy to obtain.I never worked on one but I have heard that there are a lot of private shops that have old timers that can work on them blind folded.

    Very very good engine. We still run them and go rite up into west africa with them.
    If there is a problem, normally fix them next to the road.

    Parts are cheap and they easy to work on. Cam timing is important.
    I'd say they about 20% heavier on fuel than todays motors.
    I actualy prefer them because if they go on you it doesn't cost you an arm and a leg but to drive its just not nearly as nice.

    The military used the big cam 400 for a while in numerous trucks. Lots of parts come out of surplus. You can also get surplus/rebuilt/sometimes new in a can engines from time to time. Here's a link to current listings in the ENGINE category. It changes all the time. 2 years ago I was able to buy a brand new engine in a metal can for 2k.
