I used to run a 73 dart sport , back when I was 18 , It was a 318 bored out 30 tho over with 340 heads /manifold 67 cuda rear end . nothing else . and it was doing mid 10,s in a quarter mile . Sold it when my first son was born . . 30 years later just bought a 71 Dart , 318 ---30 tho over and am starting again . Wish I had never gotten rid of the 73 . Before that I had a 1970 Valient duster(Plain Jane ). Nothing special .
