2001 Yukon XL 2500 LB7 Swap

[KEVINL]

I am starting the process of repowering my 2001 Yukon XL 2500 with a LB7
here is the yukon and the donor

 

[KEVINL]

I started the tear down and removing the cab from donor

 

[KEVINL]

i pressure washed what i could i avoided the top of the motor to prevent corrosion on injector lines

 

[KEVINL]

Started tear down for headgaskets/ headstuds as now is the time to do it and have plans for twin turbos in the future

 

[KEVINL]

A few question i have so far that would be helpful to know

are all 01-06 2500hd radiator core support the same ? Or does it matter year & gas or diesel
The donors is very tweaked

the shift cable will the one from the 4l80e work or do i need the duramax lower or whole thing?

i have heard the wiring for the drive by wire pedal is separate but i only see the large loom that comes through the driver firewall next to the pedal

is it ran in there?
Can it be easily seperated?

As for the core support i believe they are different for the different motor models. Not sure between LB7 to LLY. I’m pretty sure the LBZ is different. The shift cable i would use the whole thing from the duramax if your keeping the Allison. For the pedal that is a separate harness that plugs into the dash harness under dash cover behind the Speedo instrument panel.

I got the heads off

Iam starting to order parts
I am going to replace the CP3 it seems like LBZ pump is the way to go what about the FPR LB7 or use LBZ and get ecu re calibrated

injectors was thinking of reusing them because they werent smoking and looked real clean

but i am intrigued by the SAC injectors i hear about are these really the fix for LB7 injectors to get better longevity like the lly & Lbz injectors

also if anyone can recommend a shop to get the heads resurfaced near phoenix Arizona

 

[KEVINL]

Got the body off the suburban now to get rid of the gutless oil leaking turd 6.0

It might be gutless, but id bet you'd get decent money out of it from someone. 6.0s are a very popular LS engine.

So i finished swap end of Feburary have been ironing out some details

i had to deal with the bumper gap created by the body lift so i installed a 03-07 Sierra Hd grille and bumper
