    anything is possible, almost
    I have changed several engines, with different models and I said each time, I would never do it again
    I definitely would not tackle this project
    Is your 3116 a computer engine, Im pretty sure the 290 is not a computer engine
    To my knowledge, the topkick never had a 290 in it
    As bad as I hate the 3116 engine, I would get a rebuilt 3116 and install it back in your truck
    You will be money ahead, the engines are just too different, motor mounts Hummm youll have to make them, what a pain
    Radiators, you might have to have one special made $$$$$$$$$$$$$$$$
    air filter housing $$$$$$$$$$$$$$$$$$$$$$$
    front motor mounts
    fan blade to match radiator
    cooling piping
    relocating tranny shifter
    clutch linkage HUMMMMMMM$$$$$$$
    flywheel will probrably have to be changed, maybe a different style clutch
    The list goes on and on
    The truck is just too small, to accommodate much retrofit
    lots of headbagging

    they are called throw away engines
    They seem to work better in equipment than they do in trucks
    Cat thought they got smart and replaced these engines with a 3126, not much better
    There are some of these engines, that give better service, normally they are crappy engines

    I guess you dont need clutch linkage, you have a automatic
    call GMC?Chev and see what engines came in the topkick, then try to find a parts truck with the engine you want to install and buy the brackets, etc. If the dealer says it only came with 3116, then you have an up hill battle

    The only engines the topkick (90's models that would've come factory with a 3116) ever came with was the 3116, 3126, or a gas V8. I'm swapping an 8.3 into mine next weekend. Had an 8.3 shipped to me. I'll make a thread about it.

    Why swap out the 3116? I've always found them to be very good motors in trucks. I'd take it over the Cummins any day.

    If the truck is spec'd right and with some basic service there's no reason not to be able to do 300k+ with no major repairs.

    I'm going with an 8.3 because

    1. Its a sleeved engine so you can rebuild it more times
    2. It'll make 100 more hp than a 3116 and get the same mpg with basic mods
    3. You can run the overhead on it without $3500 worth of tools
    4. It's simply easier to work on.

    That being said, my 3116 has been a good engine and has taken alot of abuse.

    I agree with you 02dmax, my lil 3116 has been good, but it's tired now, it has a piston clicking, the front cover is leaking oil,and a injector cold flooding, the price to repair is more than what i want to spend on it, so im going to swap it out.

    A 3116 will do 250 hp with the turn of a screw and proper tuning. I have seen them at 275 hp too. We have dynoed them. Most failures are caused by improper synchronization or lack of maintenance.

    8.3 6CTA is what I did. Reliable 400hp with minimal mods. Great mileage, great reliability and super simple. I've done mine and 2 others since.
