i am kinda lost and would like to get in the right direction i have my old lly motor and was thinking of building it as i get the money but now i see everyone looking for the lbz motors and controls can some of you cutting edge duramax guys help clear it up i am looking to go 600hp daily driver am i wasting my time with the lly or is it just preference
Help: lly vs lbz motor build
- Thread starter 05maxlly
- Start date
At this stage, I've run both LLY parts and LBZ parts. Often a combination depending on what I have sitting around. Currently Casper is running a LLY bottom end with LBZ heads. Why? Because my previous build was an LBZ bottom end with LLY heads.
You will be fine with either.

Actually, I think I'm the only one that wants to take the abuse of switching over to LBZ controls :rofl:.
howabout spend the time and figure out a dsp for lbzs-lmm
i would stay with you lly just for tht reason jmo
So if I'm understanding you guys correctly, I could put a LBZ motor in my 05, and run the bottom ( LBZ) and the top half LLY? Or 100% LBZ, with NO major headaches?
I'm in debate as well to build my LLY all out, or go with a LBZ. My truck would see more truck pulls then drags. And be a occasional weekend cruiser.

You'd be fine with pretty much anything; LB7, LLY, LBZ or LMM block, LBZ/LMM (or modded) CP3 and modded regulator, but you're best off staying with LLY Heads and controls (and by controls, I mean ECM/TCM/GPCM). Switching from LLY to LBZ controls would be very difficult if not impossible if you don't have the wiring diagrams and/or if you're not electronically savvy. Heck, I may even have a hard time with it and I've done something similar before!

Eh. DSP is nice, no doubt, but I suspect it is coming for the LBZ (and maybe LMM). And I don't switch tunes too often. I'd rather have a properly functioning 6-speed Alli with tap-shift and such
