    I need some advice. i am thinking about pulling my 5.7L out of my '96 C2500 and replacing it with a 6.0L from a newer truck. my current engine is tired and worn out. other than the harness and brain box, what else should i consider?

    Automatic trans? 4l60E or 4l80E?

    I don't know about the 80E, but the 60E uses a different bellhousing between the old SBC & the LS based V8's.

    The bolt pattern is the same, however the depth is different. As is the flexplate and you'll need a LS type torque converter... I think there are adapter kits out there.

    My swap is reverse, I used a newer LSx type 4L60E behind my 350 SBC and had a custom torque converter made for that swap.

    There's nothing wrong with a 6.0, as long as you get a custom tune from Black Bear. It'll make the stock 350 seem pretty weak then.

    As was mentioned above, the bellhousing will line up (except for one bolt, which doesn't exist on the GEN III engines). You will also need a crank spacer to bolt up to your old transmission.

    Obviously exhaust and engine mounts will have to be revamped as well.

    Re: 5.7L to 6.0L swap

    look, i have done some reading cond=cerning the 6.0. i want it because it has better gas mileage than what i have. it is also more powerful. so let me make clear what i am interested in. i want to put a 6.0 in my truck, i have a line on a good running one already for a good price. now can anybody tell me some good mods for it to get more out of it. thanks so far for the good advice that has been given so far. it has been noted and will do more research. thanks

    Re: 5.7L to 6.0L swap

    I have done the swap before, its not to hard man, just need motor mounts and the flywheel and spacer to hook up to your tranny, gonna have to adapt the fuel lines to hook up, get a good wiring harness and computer tune, you can even make your stock throttle cable hook up, so its not to much of a problemb. Make yourself a good intake to work in there and other than a few tinky dinky things that you will have no prob finding arround town and doing yourself its pretty easy swap. Can end up more costly than what you expect though so be carefull on that. Also if you run you stock tranny its not going to last as long behind the 6.0 Go to http://www.hotrodlane.cc/ and they will have everything that you will need to do the swap, helped me alot. They even have a how to page where they have done the exact swap telling you everything that will need to be done and what parts you need here http://www.hotrodlane.cc/PDFFILES/Lisa%20Tahoe.pdf Hope this helps

    This place makes headers for the swap.

    That plus a tune will help it a lot.

    I dont knwo how much you want to spend or what you do with the truck but you could do a cam and converter also.

    What are you planning to do with the truck? Tow a lot? Just daily driving?

    edit: Get those headers for sure though if you can afford to. Long tubes make a huge difference on gen III engines.

    Re: 5.7L to 6.0L swap

    So do you drive it everyday?

    What gears and tires?

    I would probably just do bolt ons and a tune.

    Long tube headers, good exhaust, cold air intake, and a good tune would really make it nice, and wouldnt cost you that much money.

    Re: 5.7L to 6.0L swap

    with the 3in body lift i am running 305/70r16 tires. as for the gears, they are most likely factory. i would have to go and look and see but i can't right know because i am at work(yuck). when i can i will let you know. i would like to eventually run 35's after the susp. lift. am gonna need to know what gear to run then. by the way, this truck is currently my daily driver.
