ok, so last summer i finished a project on my '93 5.0 GT40 heads, e303 cam, GT40 intake, 30 lb injectors, 73mm MAF, and 65mm TB. Ever since i finished it, its been running really rich (smell gas bad) and gets only 12 mpg. a few days ago installed MSD 6AL ignition and that didnt help much either. Im just looking for any help to how i could fix this. i know the 30 lb injectors are overkill for a n/a motor, but i wanted to leave room for improvement. any help would be appreciated!
