I am doing the 6.2 swap and it comes with 40# injectors. How much HP can my stock 5.3L fuel pump handle?

my truck was just on the dyno yesterday.. i have 52lb injectors and he was tuning it with the new cam install he managed to get it to 470rwhp but the fuel pressure started dropping because of the fuel pump.. maybe that will give you an idea? he backed it off to 463rwhp and everything is fine..

I believe that answered my question that i need to order a walbro fuel pump.
