64-5 intake bolt angle

65 is the valuable one year only, maybe $100 to 273/4bbl wannabes
66 not so much as it has the modern bolt angle but will fit all >65 273-318s so maybe 60?
D4B is probably the most desireable as it is the 64-65 only (bolt angle) aluminum 4bbl intake. $150+ but one went for 250.
But as always it is the value to the buyer that sets the sold price.
