1986 Lincoln Towncar. That thing was awesome! The engine blew in 1991, the previous owner (a friend of my fathers) has a good friend that works in the R&D section of (what is now) SVT at ford. They had a bunch of 5.0L left over they were getting rid of they were HO engines that were used as test motors in what would become the 1993 Mustang Cobra, so my car was treated to one of them. When i finally received it, it had about 50K on that engine, so i proceeded to warm it up a little bit, exhaust work, work a few others. The exhaust note on that thing was NASTY. I had limited funds but still that car did a high 15-low 16, that's not too bad all things considering a stock 2003 Marauder does the quarter in mid 15s. I wish i still had that car and the money i do now. You'd be looking at a 13 second towncar, especially with the 351 in my shed looking for a new home. I miss that car
