Last ls question before parts get ordered

[jstrong394]

I planned to go carb'd on my 5.3 into a 85c-10. Well the intake is on back order. I started thinking. I have to get intake, timing control msd and think I may get a new carb then the one originally planned to use. My engine is complete without harness and accessories. I know I need the fuel system setup. But would I be better off going fuel injected. Other than the accessories wiring harness and fuel system setup. What else would I need. Started thinking it maybe cheaper to go efi, instead of carb'd. Second guessing my decision. One last post before it all starts lol
