Are you sure? I'm pretty sure the04/5-06 LLY is the same as the LB7, and you would have to change the intake runner on the LLy to make an LBZ bridge work.

Look HERE I started a thread on this awhile back. Should answer a few questions, and probably cause a few more.

To swap to an LBZ bridge you need to swap to the LBZ/LMM runners as well. There is no need to do it, the openings on the LLY flanges are both bigger than the one inlet(intake horn) that feeds the two of them, even with the aftermarket 3" OD pieces.

If anything will help, it would be getting rid of the smaller intake horn and going to the one that Rick makes and is slightly larger.

The LB7 bridges are actually larger inside than the LLY's, and they do have the same flanges so mating to the LLY intake runners is not a problem. POSTED BY: [email protected] SDP

Will lb7 y bridge fit on 05 lly????
You'd be better off just going with an LB7 up pipe and a full EGR delete bridge (Profab, Allseason, etc).

Just my $0.02

I have an Lb7 van bridge on my LLY. If you check out my twin build you can see it.
