700cc injectors says that he won't be making 350rwkw on E85, they're not up to the task. Dave (NYTSKY) is on 1000cc injecotrs now, and so is Anthony (Guilt-Toy) I believe. Anthony also has a 3L bottom end. And I don't think he's running a 3076R, I thought it was a 3540...
So with the combined facts that a 3076R won't make 350 unless on E85, and the fact that 700cc injectors won't run 350 E85 rwkws, and that the original poster never mentioned E85, Nismoid is right.
That turbo, with those injectors, and either fuel, will not make 350rwkws... E85 will get you closer, but then you will have to up your injectors...
