injectors
 

i have a 1995 5.0 gt with gt40X heads, e303 cam, full msd ignition, cobra manifold and intake, cold air, 65mm throttlebody, short header no cats h-pipe and mac mufflers how much hp gain will i get with 24lb injectors? i loose power after 5000 im guessing due to stock injectors

Injector's don't add HP they support make your currently making. Is the car running lean up top?

I am guessing that it has more to do with the cam and shorty headers but you'll want to do a tune and check out your A/F ratio. If you're leaning out and your injectors are at 100% on the duty cycle, then that might be the answer. Another thing to keep in mind is those intakes (all long runner designs) are made for low end power (unless you're forcing air in there with a SC or Turbo) I am guessing your car is pretty mean on the low end
