Wasn’t sure where to post but here is my mostly complete 74 duster 360

Did that to my 1976 Dart Sport about 15 years ago...essentially the same car. I took out the slant and dropped in a 79 360 out of a Ramcharger, had it rebuilt, shaved the heads to 9 to 1 comp. added an Edelbrock air gap intake, 4 bbl carb and presto...325-350 hp at the crank.
