Well, just do a calculation on fuel flow at 600HP.

Returnless or return? Anyway, it may not be the fuel rail that is the issue, it could be the feed line from the tank.

Anyway, you can figure out the max flow that the engine will require. I guess it might take around 60 lb/hr injectors. Then just work you way backward realizing that at 80% duty cycle on max flow times six injecotrs.
Thats like a total of 288 lbs/hour, and gasoline is probably 6.2lbs/gallon, so that would be around 46 gallons of fuel per hour. 3.8liters per gallon means that is 177lph fuel flow.

Now if you know your flow velocity and the diameter of the rail you can determine the minimum required tubing size. Then multiply by at least 10% for a little room for error.

In the VERY worst case you can just have a custom fuel rail built. However, I'm gonna take a stab that 600 hp might be around the limit but still enough fuel to support it.
