Should base your selection on the designed rpm range for the engine. Match the components to match REAL WORLD rpm, not what you wish it could run. With the cast crank and hypereutectics, you may want to limit your projected rpm and pick a cam, intake, and carb that will work well together. With the vacuum secondary Holley, getting the correct secondary spring and power valve will also become important. IMO I would use a cam, carb, and intake that will perform well to about 6500 rpm.
