HOLY COW!!! Not to trying to be a duche here. But who built the motor? What Im getting at is, did they check the cam? It would suck to get it all together and it not be an AF cam.
I'd stick with stockers unless you plan on tuning. Aeromotive is a good pump, similar to PPE's. But anyways do a fuel return test. You might only need to replace the one. But its always a better Idea to hit up brent for all eight. Its a bitch to tear the motor apart to replace one and a few...
Yes thats EFI live but I dont recommend it. Will not that tuner anyways. Id get EFI from one of the vendors here. I personally recommend moonshine! Get the tunes you want for the mods you have. And get the cts you can change tunes and monitor engine vitals.
