I just bought my first Mustang, a 1995 convertible 5 speed. Body and interior are good, has ss MAC exhaust from manifolds back and a cold air intake. Other than that is stock with 220k miles in it. I want a 400 foot pound torque, tire shredding, stoplight beast that can still run 70 mph on highway to the beach. I would like advise on the easiest and least expensive solution. Thanks.
