12/9/2023 0 Comments Bluex build thread gmt400![]() Stock 元1 power steering pump bolts up to LS power power steering truck bracket. I am going redo them soon to braided lines. Stock trans cooler lines are pretty tight to the ls oil pan but worked fine with a little love. Sewlow recommended it on so I decided to give it a shot. Currently have my oil cooler port blocked off on the engine but will run new braided lines soon, you will need 20mmx1.5 to -8an fittings for radiator. Used stock ls truck radiator hoses with some trimming Lextech AC/alt brackets (haven't installed it yet, maybe next week) stock exhaust manifolds with home fabbed exhaust to connect to my existing dual x-piped exhaust Dirty dingo 4wd k1500 engine mounts part# DD-2575-4 2006 Lq4 flexplate with spacer that came on my engine engine is a heads/cam 2006 Lq4 (24x reluctor) I had a marine vortec intake on my 元1 so I had already redone my wiring for external injectors. then reworked my stock harness to work with the LS engine and added a couple wires from a spare 01-02 truck harness (coil wiring, knock sensor wiring) Started with 411 swap and made sure everything worked right Thread starter jcloud Start date Disclaimer: Links on this page pointing to Amazon, eBay and other sites may include affiliate. If you use your own transmission from your Tahoe, you will need a 4L80e flexplate and spacer from a 01+ Lq4 6.0L in order for an LS engine to bolt up right to your torque converter. I believe the 03 van computers are the 1k blue/green connector PCMs. Not sure on the 03 van computers but using the 411 PCM in our trucks for an LS swap is pretty straight forward. I just completed my LS swap into my 1999 4wd 2 door tahoe w/ autotrack transfer case (np8) and everything works right, gauges, 4l60e, abs, evap, etc. maintain gauges & ABS.Īppropriate engine mounts to keep 'stock location' Repin LS & Vortec harnesses to work together. do I need to stick to the 411 computer, if retaining my original trans, or will the '03-04 6.0 express van computers work? I am unsure if these are 411's. instead, if I get a full engine & trans out of a 4x4, will that LS 4x4 4L60E bolt up to my stock transfer case? I have the autotrack deal, which I have no intention of changing (yes, I know my stock trans will need a rebuild upgrade w/ more powerful LS) the '01-'02 or the '03-'04 DBC examples above will correctly control my stock 4L60E? I may have to request torque management changes w/ a reprogram. I've searched & browsed but haven't seen clear specifics: I may consider a 5.3 but for now i'm looking for a 6.0. I'm considering any '01-'02 LQ4 DBC, or '03-'04 Express Van LQ4 as these are still DBC. I'm investigating an LS swap into my 2000 Tahoe Z71, which is the last of the vortec 5.7 OBS, and I have some basic questions.
