Stock Throttle Body Pump, 500 HP?
My 305 L03 1989 RS camaro is probably getting my fuel injected / blown 355 engine real soon.
can the stock TBI fuel pump feed enough fuel to my new Holley Throttle body injection setup to support my blower?
It comes with an In-line TBI pump, can i just disable the in-tank pump and leave it in there and use the In-line pump?
Or should I run both for safety? Or should the in-tank pump work?
Or.. should I get a new in-tank pump and replace the stock on? If thats the case, whats involed in dropping the tank?

itll be a real restriction. Your bes bet woudl be to sump the tank with larger lines. The pump will impede the flow of fuel. You could try a new in tank but 500 horsies is going to require alot of fuel. More then the stock lines can probably supply.
