Could or would lml injectors fit in a lly head. I think the lml bodys are smaller in diameter but would they fit in a lly head. The reason i am asking is i have a built lly motor with ported heads and valve train upgrades. It would be nice to put that engine in my lml. I know all the other stuff i have to do. That is not a big deal

Just dumb me thinking. But because it has a larger oring holding it center and isn't centered on the body itself (assuming) how is it ever going to stay in place?

The o ring on the injector is only there to seal out debris. You could run without them in a pinch.

Finally got to work on my truck and engine. The lml injectors fit perfect with lly heads. You just run the lml lower valve cover and the upper valve cover. The orings i used were 15.8 id and 20.6 od and they held the injector nice and snug.

As our trucks get older it is going to get harder to maintain them and some people have tons of $ in the built LLYs , now we know of a new option thanks to your tenacity !

Now to make it run off them. How do you plan on doing that?

Does anyone know if you could run lbz/lmm injectors in a lml head?

I am going to do that here shortly. The injector bores will have to be drilled our some but there is enough material in the head to do that. I am going to do that in about 2 weeks. I am going to put the lml engine that was in my truck into my boat and use lbz injectors and electronics.
