Edelbrock D64
If you bolt the D64 intake to 360 heads, the pic below is how far out of whack the bolt angle will be. Pic was made with an Edelbrock D4B, which was made to fit the 64-65 273 motors like the D64 was. If you use a D66, the flat washer on the intake bolt will be at the same angle as the pad it will hit on the intake.
