Cause when i look under the hood i want to see it. And not have to listen to every so called expert at a cruise night bust my balls cause the tag is gone. Your right i don't care about numbers matching but i do like them to look orignal as possible. Granted i can't hide the Holley street dominator intake and 750 Holley carb but i did paint the intake stock engine color and did order the fuel line kit from Fabulous Fabracations to look more stock..
