I bought new injectors and I need to run 1/2 adapters to make them work with what I have. I was wondering if I.change to aftermarket fuel rails if I can eliminate running the injector adapters ??? Im running a 5.3 with ls1 rails return style im assuming

 

I am curious, why are you against running the spacers? Guys do it all of the time.

 

Not againest at all. Im thinking about buy new fuel rails also and if I can do this without buying adapters then I would just go that route and save myself $100

 

Depends on the intake...ones like the holley have multiple mounting locations to account for different height

 

Holley efi 534-209 is the rails I was looking at, it comes with multiple brackets for factory intakes..
