I need to get an in-tank fuel pump for my new setup and I have asked before but no one seems to have a part # for me.
I guess I'm suppoed to hot wire the thing too because the stock pump has spikes and changes PSI all the time.

I don't know what the Walbro# is, but I used the Holley 255lph pump here:

I honestly don’t think any intake pump will handle 600hp.
I used the GSS340M 255lph with hotwire kit on my stock engine, works like a charm. That’s about the highest flow you are going to find from an intake pump. You can get it here: http://www.racetronix.com/product/RX..._Pump_Kit.html
What engine setup are you planning to pump 600 hp out of?

600hp....
Well to get 1 thing straight....I will not be using a computer, so I need a pump that does not require that link ( not sure if the one you recommended does or not).
I have a 3 outlet regulator ( Mallory) already in the car. The problem at the moment is that I get PSI spikes all the time. It jumps from 5 psi up to 8 psi all the time because of the computer.
Anywho, the motor will put out at least 450 hp N/A.....then I am planning on a centrifugal blower to boot.
355ci w/ trickflow heads and over .500 lift of cam. 9.5-1 comp.
It's gonna run.....
May possibly be looking at over 600 hp....easily depending on which blower I go with, but 6 psi will be tops.
