LLY and LBZ/LMM injectors

[bobxr50]

Just wanted to confirm info. You can run LBZ LMM injectors in a LLY? Older info in the past states that you cannot. Just wanted to clear it up either way.

Opposite. The LLY injector body is straight whereas the 06-10 has a slight taper causing the LBZ/LMM injector to not seat properly in the LLY head.

If you have a friend with a lathe, .015 off the Lbz/LMM body of the injector resolves this issue.

Totally understand about the sizing issue. I was wondering about the ECM/FICM. No performance loss with the LBZ injectors vs LLY

It may take some tuning work to make it run/sound smooth as lly Fire off 48v and lbz Fire off 24v from what i remember. Couldn’t answer longevity. They will run and work though
