I think I saw in several threads 485hp not sure, but I know the new c5 vett has the same pump and their 500hp rated, if your not going to crazy install a inline,injectors all depends on your mods but her is a site that may help you with your pump issue good luck,

It seems that I have read the entire full system(rails,pump,injectors), would be good to about 500hp. Not sure of the direct threads off hand maybe someone else can chime in.

When you say modify are you speaking about the walbro 340 have to be modified at 500hp or are you saying the 340 have to be modified to be installed?
