I have use the Indy brand M.W. size intakes with both 4150 and 4500 type carbs, if your running a high deck motor the 440-2 intake is the part # for the 4150 type carbs, 440-3 for the Dominator flange carbs up 400-2 and 400-3 for the low deck motors.
BTW I have used and liked the 4500 type carbs on the street after some tuning on them, they work great work up scope
in todays world of custom built carbs and the increased competition to Holley there are many good choices on a new bigger carb, more airflow and fuel= More power in every BB Mopar I've tuned and drivendevil
