I am awaiting delivery of a 2006 L33 5.3l engine. I plan on using a 228r cam, ported throttle body, 1 3/4 headers, and either a truck or tbss intake. From what I have read about others experience, I think I might need slightly bigger injectors. If so,how big should I go. Would a truck intake with flex fuel injectors be a good option? I know there is a setup with intake, injectors, harness and computer for sale in the classifieds right now. I will need a computer , and harness with this engine so this might be a good fit. What do you guys think?Just to be clear, I never plan on using another fuel. I just know flex fuel injectors flow more. Thanks for any help or advice!

Do you know what size injectors are in it now? About 30 lb injectors should feed that, but if your going to buy some I'd go 36 or 42s.
