Default What fuel pump for my setup? Inline or Intank?

Hey everyone, just wondering what fuel pump I should use? I am running the cam in my sig and will be adding some ls6 prc heads in the next few weeks and im wondering what fuel pump I should go with? The 255 lph inline or 255 intake pump? Or should i go with a different one and which one? Also, im looking at either svo 30# injectors or lucas 38# injectors. Can i run either of these injectors on the stock fuel pump or is that a no no? Thanks and any info or suggestions on a fuel setup would be awesome!

I prefer the intank pumps because an inline still leaves the weak link: the intank pump. I did my walbro intank and it isnt difficult. For injectors i would just get the 42Lb SVO's since they are enough for most future projects you may come up with, they are cheap (around 225 shipped here), and they are pretty easy to tune for and will idle good.

Either injector can be ran on the stock pump.

intanke pumps appear more efficient and a bit stronger. Go with the Walbro 255 from NewEraPerformanceParts.com Best price i've seen. I'm running 42#'s and this pump. Be sure to get flowmatched injectors!

Ok and by flow matched you mean? I will have the car fully tuned but do they need to be flow matched to whatever fuel pump im using or? Sorry if its a stupid question, im just completely lost when it comes to fuel systems.

Flow matched means that all the injectors will flow exactly the same as the others.
