OK, I'm dumb, need help

Friend of mine has a Dart 4 dr sdn. Slant six, FI, turbo, 200R4 trans. Drives it all over the country, including to the drag strip. Runs mid 12's in the 1/4 mile, and mid 20's MPG. Granted not a low buck project, but he did most everything, himself, except for the trans build, and conversion parts.
