Ik this prob been gone over a hundred times. But just got some questions. I got a 95 f150 with 351 with a 5spd . The motor is geting tired starting to smoke so I want to pull the motor and and have it built. I'm just wondering what can I actually do to it and have it run right. I was thinking of puting heads and intake and a cam in but I've heard where it don't have a mass air sensor the fuel injection won't compensate with these add ons. So what can be done ? Do I switch to carb or will it run fine
