I have a ly6, and i want to rune the ls3 intake or the Truck intake, it is on a aftermarket EFI, so the injectors will not be a stock injector, My question is can I use a aftermarket ls1 fuel rail on a ls3.

basically what i am looking for is - are the spacing and the angle of the injector the same?

I know the mounting is different but i can fabricate all the small stuff, mostly concerned about the spacing from one injector to another and the angle that the injector sits at.

I'll let you know in a few hours.

I was wondering the same thing, but just received my LS3 intake and have a set of aftermarket fuels rails at home so I am going to check tonight.

Not without custom mounts. LS1 injectors are the longest, LS3 injectors are the shortest.

Spacing and angle is the same for the injectors, but rail mounting is in a different location.
No big deal, just need to make some custom brackets.

You will probably need a different bracket to mount the fuel rail. LS1 fuel rails will typically mount higher off the intake because of the taller injectors.

Thanks guys, I have a small 9x42 mill and a 16x60 lathe I will post what the brackets will look like middle of nest month.
