Which size fuel pump LSX swap

I am doing a LSX swap that should be in the 425-450 HP range.. I am leaving all the stock lines, tank, etc on my 92 coupe.. plan on plumbing them into my feed/return on the intake... what size pump would anyone suggest?

240 or 320, I used the corvette filter regulator that has the return built in and set at 58 psi. works good, I've had this way for over 12 years.


93 Coupe, Reef Blue, a/c, 3:55's, 10 holes,
1/8 6.56 @ 103.23 mph, 1/4 10.37 @ 128.49 mph 1.43 6/06/15
1/8 Nos 6.06 @ 114.71 mph 1.38 12/16/15
1/4 Nos 9.879 @ 135.29 mph 1.39 12/19/15

I'm using the DW300 from Deatschwerks - so quiet you can't even hear it prime. Plenty of capacity to service my LS3 at 58 psig. Standard Fitment Fuel Pumps : DW300 In-Tank Fuel Pump | DeatschWerks
