Ls7 Fuel requirement

Can a f-body fuel pump support a 434ci ls7 or will i need to change it out? If so what should I use that would be a simple swap with little modification?

If it's an LS1 car it will be just fine!

You'd better keep an eye on it. You're going to be at the upper end of what a racetronix can support.

this is going to be my DD, looking into it im thinking i may need a racetronix f99... im only expecting 550rwhp or so on 93 octane. Just making sure to get everything in line for the swap. Does any one know how long those pumps last? would only like to have to change it once
