Thanks. Just so I am clear I have an 89 F150 with the 302 and about 256,000 so the old dawg is pretty tired. As long as the plug wires are on the correct cylinders the 351 will work, right. The other question I have is if the motor I found will work. It is a 96 model 351W complete from intake to oil pan. I was just wondering if it will work with my EEC-IV computer cause it is a roller motor.
