5.4L Roush supercharger
 

Sorry for the Ford post....
Good friend of mine is selling a Roush Supercharger Kit. It includes everything you need from the blower/intercooler to the ECM with a custom tune. He had it on a Mark LT pickup and he was in an accident. He bought the truck back and parted it out. He's looking for $3,000. It has about 7,000 miles on it. Also has a full roush lowering suspension for sale. Not sure of the price on that yet. All parts and hardware are there. I personally drove his truck and it had a good amount of power... for a Ford. He can answer any questions. Pm me and I'll put you in touch with him.

For a 3v I'm assuming ?

I believe so. What ever motor is stock in a Lincoln Mark LT
Confirmed 3V.
