    Well this was going to be a donor truck for the crew cab but I had no luck find any cabs or anything for it. So I will now just be fixing up this truck

    1994 cummins 308k miles, 5 speed. No blow by from I can tell.

    Plans are to go through everything replace most wear parts change fluids. And then I will dye all the interior black and do something about the seat inside. Then finally it will be painted, I'm not sure what color, but it will be some sort of silver or gun metal.

    Performance mods planned, are 3k GSK, new intake, BHAF, boost elbow, and 4" exhaust. I don't want to get too crazy just a little more power and mpg's. Edit: and fuel plate

    The truck was 0 I hope to have less than 4K in when done, but we know how that goes.

    I think I want to black it out too

    It looks kinda cool and everything on this truck doesn't look too good so painting it body color (gun metal) or black will make it look nicer

    Oh I lied, I blended to of my previous dodges. the grey one was ext cab 4x4, the reg cab 2wd stick was green.

    this is usually what mine look like after I'm done with them.......

    I found a extended cab that had a cummins for $800 bucks. It about an hour away. It has a gooseneck hitch already and the bed isn't rusted out. And what body panels are damaged are in good shape on my other truck. The dash is cracked also, but it's not on my other one and the gauges seemed to be in better shape.

    Seems like I cant go wrong there

    The extra wheelbase will probably help towing also, we plan on getting a gooseneck to hold two trucks, probably about 15k pounds.

    :sign12: , Really though cummins are freakin legendary. If i wasnt so retarded with diesels id probably try to get one for a tow rig. Only thing im any good at diagnosing and fixing is carbed gas motors though :doah:

    The diesel seems to be much simpler than a carbed engine

    The 12 valves are about as simple and easy to work on as it gets, not to mention they are built stupid strong.
    Since you are thinking about a custom flatbed, check out the old project truck Fourwheeler mag did, project Baja Bomber, it was an extended cab cummins with a race recovery oriented custom bed. IIRC it was a pretty cool design.

    As far as your mod list goes for the engine; do a 4k gsk, look at a AFC spring kit, don't waste your money on a fuel plate, either grind your stock one or just ditch it all together. Also look at a Mack rack plug since you have a 160 pump engine, and I would put some more timing in it especially if you haven't checked the KDP yet, since you need to remove the front cover anyway. A mild set of injectors could be nice as well, some great rebuilt ones can go for as little as 350- 400 after core charges, more power and better MPGs you can't go wrong :D

    The idea of an injection pump and its sensitivity to air in the system is mainly what throws me off.

    that doesn't make any sense at all. in any normal, proper working system there is no "air in the system" a stupid gasspot with porus fuel lines is going to give you just as much trouble as a diesel. but its way easier to diagnose. pull the return line and run it into a clean clear container, if its airaided in the return line you have an air leak upstream. find it, fix it, be on your merry way.

    I'd think you'd want to do delivery valves before injectors. the 160 pumps respond really well to 181 191 or 022 or lasercuts even. A buddy went and tryed all of them in his minty 1995 reg cab dually. he stayed with the lasercuts. and wouldn't bother with a rackplug honestly. if you want to really get into it maybe but not nessiccarily now. you have to remove the pump to access it anyways. definately set timing to 16 degrees BTDC. I'm not sure why you'd want to mess with the AFC. if you throw the plate out the AFC is a moot point. just gut the AFC housing all together and drive by peddle.

    How hard is it to pull an engine out and put it back in? If it's not too bad it seems like It may be worthwhile to do it. I could do the KDP and rebuild the head and do some port work and new stainless valves. And do all the stuff to the injection pump. It would be much easier with the engine out

    I could also pick up that extended cab truck.

    It seems like pulling it would be a pita though

    you generally. drop the front clip, rad and cac. leave the tranny in, lift the engine straight up as much as you can. you have to drop the oil pan and pickup tube. then it rocks right out.

    Yes 2wd

    Do you have to take the front cover off to change the pump timing? I'm about to do the KDP mod

    It looks like the timing is kind of involved though, maybe I'll just end up leaving the timing in the stock position unless I can get the tools or find someone to do it.
