340 Demon parts Car

The Dart was a 6 cyl. I installed a 74 K-member and plan to convert to 4 1/2 inch bolt pattern! I also have everything besides the trany to convert to 4-speed some day! It has a 318 at the moment! i also found that the 340 in the Demon is a 72 engine!
The Dart is Soild under and straight. I am planning a complete overhual over the next two years.
