what would be a large enough injector for a heads( richard's 6.0 vortec stage 2) and cam (something around a TR220) 6.0

i'd like to come out with about a 60-70% idc

it wont be getting forced induction or nitrous... i suspect i will need more than stock but dont think i need 42 lb'ers or higher or will it be just as easy and cheap to go with 8.1L injectors

 

and would a single walbro 255lph fuel pump be enough

the only reason i would replace the fuel pump is because it is whining real bad and i want to replace it anyways

fyi all of this is on a 4.8 truck i got a new truck but havent got pics yet so that's why the sig isnt updated

 

i ran svo 30s on my truck and was only at 74% with my setup. thats all you really need for most applications

 

is svo an aftermarket company ?

 

the walboro will be plenty.

 

I believe that they're Ford SVO injectors
