Owned a couple cougars rebuilt a few 3.8s na and sc, never owned either a thunderbird or a 3.8 sc before. Recently purchased a 1990 35th anniversary SC that needs head gaskets, so looks like the first mod will be is completely ported and polished top end and manifolds and gut the exhaust as well as delete ac and smog. Arp headstuds are on the way, ordering 97 3.8 mls gaskets in the morning. Custom tune at the shop I work at (horsepower solutions) and drive this thing everyday everywhere. Owned and built a few racecars in my life and with a 2 year old little girl it's just not what I want anymore, want more time with family than wrenching and vehicles that won't let me down.
