HVH Super Sucker On 360 Magnum

ya I can try a 2 inch 4 hole phenolc spacer for around 30 dollars. And I have been doing more reading and found out that the tapered 4 hole spacers show gains when the carburetor is too small for the engine because it enhances flow. I don't think a 680 cfm quick fuel is too small for a mild 360 magnum. Do you?
