Dodge Dart 4-Door 1964 - Coming back to life

Welcome, and nice little project you have there! It looks like the 273 you bought has the exact motor mounts that you will need to drop the 273 into your Dart. If that engine came out of a car that is being parted out....hurry up and go back and get that V8 center link for the steering. If you are REALLY lucky, and the motor and transmission you bought came out of a 66 A body, and all of the linkage for the transmission will still be available, you can grab that too. Good luck with the project, and I'm looking forward to watching it come together. :)
