Ls 6.0 bored and stroked to a 408, AFR 210cc heads, Comp cam 54-426-11, Still running stock intake for now. About to go get it tuned finally. I’d imagine I need fuel pump and injectors but I don’t know much about them. Any suggestions would be awesome! Thank you for your time.

 

I'd say the standard 255LPH pump if staying NA and regular pump gas.

Injectors I'd go straight to some 50-60lb/hr injectors. Either factory 50lbhr or 52lb/hr from a GEN 4 truck or go with a the similar size from a company like Fuel injector clinic, Fuel injector connection or deatchwerks.
