Ok I have a 91 with a 5.0. I just did a top end kit on it minus the cam. New 185cc Patriot heads, used Trick Flow Street heat with 1/2" spacer, 75mm throttle body/EGR spacer, 4" Anderson tube, 90mm MAF set for 24lb injectors, 24lb injectors, and new 155lph fuel pump, 1.6 comp cam rocker arms. Ok...
