for 320rwkw, a GSS340 is plenty for an in-pod pickup pump and provides the pickup abilities for surge-tank setups if you go that way for more power in the future.

Plus if you went the 460, you'd have to modify your return and possibly need a new regulator to keep your fuel pressure correct.

My FG is about that power and I've got the pump Keith mentioned above. You could probably get away with a factory FG pump, but I'd rather know the pump could easily keep up.

If you buy the 460 you will need to switch the fuel regulator, GFB make a bolt in unit that's will solve the problem.

the issue is the stock reg has quiet a small return hole, so when you get a big boy fuel pump the fuel cant actually return to the tank fast enough and you end up over pressurizing your fuel feed.

You will also need to upgrade the power cables to the cradle, as that pump will eat around 22amps and the stock wiring is proberly only good for 14a.

 

320 Kw you will proberly only need around 200 LPH of fuel flow, have you considered just using a 255lph drop in fuel pump?

this would mean you dont have to change the fuel pressure regulator, nor the wiring.

 

if you plan to use the car in a way that the fuel will slosh around, like hard cornering accelerating for bulk periods of time, then you might actually be better with a surge tank and pump setup. for that power level you could use your stock in-tank pump as a lift pump and fit whatever pump you want tot he surge tank to guarantee its allways got fuel flow.

usually the surge tank will be closer to the engine bay to, so running the upgraded fuel pump wiring is somewhat easier.
