So I'm in the midst of putting together my first ls. It's a lm7, completely stock bottom end (new rings and bearings, that's it) tick performance torquemax stage 1 cam, professional products typhoon intake and fuel rails, 85mm throttle body, headers,etc. Which injectors should I lean towards? Any suggestions for size/brand?

 

So from what I've figured, I probably need around a 30 lb injector. We're any of the factory ls injectors rated around that?

 

most were 28.8LB @ 58psi rated.

grab some 30# @ 43.5psi rated or even 36# @43.5psi rated injectors, it will give you room to grow and they will run fine.
