Hey guys, I did a search but could not find any info:

I might have the ability to get my hands on an 6.0Ltr V8 (316-hp) engine out of my Buddies 2003 H2.

How does this 6.0 differ from the 6.0 in my 06 Denali Engine Code: LQ9 (364Cu/in - 6.0L-345 HP/380 lb-ft. of torque)?

How hard of a transplant would this be in my 1999 GMC Sierra 3500 (Classic) Dually? What would I need?

I'm assuming that I would not be able to use the Hummer's Transmission since it's a 4wd and I have a 2wd so what Trans could I use?

Any other thoughts/issues from others that have done this or know how to do this would be greatly appreciated.

TIA

im not sure of this would hel but i have a 87 6.0 in my 1980 dually and it has a turbo 400 wouldnt know if the motor has changes its bell housing mounts or not but that what i got for mine hope it helps

i bleive you have to yuse a 4l6e trans... there are conversions kits i bleive i will see if i can dig any up... shouldnt be to bad a swap... usually difference will be in tune or intake or internals sometimes on motors

You can use your existing transmission.
