The Great Pumpkin - '71 Duster

I like the longer tech write ups, the details , make the difference in the end. Sorry to hear, about the engine situation. Like your taste in manifolds, have had nothing but good luck with Holley Street,or Strip Dominator manifolds. FWIW : stroking it to 372( and a lighter rotator assembly), usually demands more airflow.( and usually drops shift points...) I like it. Will be curious on choices for cyl head , converter & gear choices . Best of luck
