horsepower comparison chart
Found this on http://racingbeat.com
Thought it might prove valuable here.

The following chart lists the approximate possible peak horsepower output of various intake systems offered by
Racing Beat. These output valves assume that a header and an open or performance exhaust is being used for each application. Since stock horsepower output varied from model year to model year, the values listed are approximateand
reasonable estimates for each engine/intake application, your actual output may vary.
