You need an H.O computer.I have a couple of Mark VII computers in the garage that are Speed Density,and in great shape.
Wrong answer... With the introduction of port fuel injection in '86, all systems in passenger cars(not trucks) are SEFI.On 2006-02-23 10:21, raheed2 wrote:
The injector firing order on a speed density computer does not matter as they are bank fire. The 86 Lincoln came with 14lb injectors and a restrictive upper manifold. They also had a 50mm throttle body. You need to get the upper plenum ,EGR spacer and 60mm throttle body from an HO motor. You would also need the 19lb injectors. You will also need a speed denisty computer from an HO motor. If you use the set up you have the motor will be starving for fuel.
