Buying My First Muscle Car 1973 Duster 340 Interior Pic

My opinion would be to get it running and driving in any condition you can. Too many people blow these things apart then they never get put back together and lose interest. Do what it takes to get it running and driving and then you can take it down for a couple weeks for this or a couple weeks for that and not get discouraged..
Did somebody just tell you it was a 340 or have you looked at the Block and seeing the numbers?
