Well, I put the stock throttle body back on and the whistle went away(thanks Racingrick). The stock tb has a hole in it, and the BBK/Edelbrock does not, I suppose that is the reason for the whistle. Here is a picture of the finished product. The new combo definitely flies, just waiting to get it on the dyno for some fine tuning, and some numbers. Thanks for the help all.
