Its a bright red 65 Dart 270 with a clutch pedal. Been a race car most its life and i got it needing some assembly. Ive uploaded the tag - ive tried 4 or 5 different sites and about 2% of it makes sense. According to one its a 119" plymouth. Another says dodge 880. Another says its a 273 2bbl but then another says 31 doesn't exist but 30 is the 273 2bbl. Its mind bogglin.
