Ok, so i'm having a little difficulty figuring out what fuel injectors I need for my engine. By the time everything is said and done it will be a 5.1L with TB, CAI, full exhaust, pulleys, performance water pump, ported heads, spec stg 2 clutch. Will my 24lb injectors support this, i'm guessing over 400 engine hp at least. Is it possible to get injectors too high? I was thinking maybe 42lb for adequate fuel when forced induction comes into play. Any thoughts would be extremely helpful, i'm stuck on this one. Also will I need to upgrade the fuel rails?

you could run your 24# inj on the dyno and see how much u can get out of them, then swap over to your 42# inj. i would think i wouldnt make sense to buy something in between if you are planning to go with f/i. i would think with a 5.1 mod with f/i 42# might no be enough for u. you can go to the ford racing website and they tell u how to calc what size inj you will need for you anticipated engine hp level. if you plan on getting a s/c dont buy pulleys, first off they r a waste of money and 2nd, they have to come off for a s/c anyways. also, i would say get some cams to make the most out of your ported heads since i didnt see that on your mod list.
