I apologize for lack of details. I tend to attract the internet experts (be it Ford, airplane, or motorcycle) that like to explain in great detail how much they know and my ideas are stupid and will never work. My question never gets answered, so I tend to just ask the question with minimal detail.
I am building a 351w with mildly ported GT40 heads, "bigger cam", Edelbrock intake with twin 56mm throttlebody, and a stock 75mm MAF from a 95 F150. Using the Cobra X3Z computer because it is preprogrammed for 24 lb injectors and my math calculated I need 23.16 lb injectors.
This is all going in a 90 F150 with a 5 sp manual transmission. I am converting from SD to MAF.
