My motor is smoking and down on power. It has 200,000+ miles. I found a 4.6 locally out of a merc marq for $400 71,000 miles. The motor is still in the car and runs fine. Is the long block the same as a 97 GT? I am pretty sure it is a non pi but maybe the forum can tell me more. My car is more of a cruiser and a show car and the smoke is embarassing.
