5.0 EFI upgrades?
#1
i can get a GT40 lower/upper intake with 65mm throttle body and 19lb injectors cheap. my motor is a 1991 mustang GT 5.0 HO,bone stock with about 18k. using a A9L,RJM, and WH's shorty headers, and 2 into 1 2.5" exhaust w/ 1 flowmaster


1) can i install these parts and use the stock A9L?
2) will any of this hurt gas mileage?
3)will the air fuel ratio be way off?

i have a built 306 with a nice cam...trickflow roller cam 499/510 lift

i would eventually like to swap that cam in the 5.0 EFI and maybe upgrade the A9L to accept it...so im thinking these parts...along with GT40 heads...would be a good combo.

any thoughts from you guys would be help, thanks...Chuck
