Will the performance parts that fit a 4.6 mustang fit a 4.6 lincoln town car?
Yes, they are the same engine almost everything from a mustang 4.6 Modular engine will fit you 4.6 Lincoln. The engine was place into the Lincoln first in 1991 before they place it into the Mustang in 1996. Just like the Mustang Cobra 4.6 Modular engine which is the same engine place in a Lincoln Mach VIII. The Shelby GT500 and Ford GT is the same engine as the 5.4 Modular engine in the 1999 on Lincoln Navigator except for the supercharger.
