1998 Lincoln MK VIII

Hello all. This my first post so I hope it goes through. Years ago I purchased a 4.6L DOHC from a low mileage 1998 Lincoln MK VIII. I'm finally getting ready to put the motor back into service. Since I do not have the wiring harness I plan to utilize the MSD 6011 ignition.

For fuel, I would like to use a high rise aluminum intake manifold. My plan is to use the Holley Terminator X stealth which mounts on the standard 4150 base. I FOUND THE PERFECT MANIFOLD. IT IS A SULLIVAN PERFORMANCE 101 B. . Problem is they do not return my phone calls. Does anyone know their whereabouts, or can anyone recommend a different alternative.
