Thanks for the replies! I have a shaker hood for my wifes cuda, but will have to buy all the other parts aftermarket. It would probably be cheaper to buy the stage 5 intake than do all the mods needed to the stocker. I have heard mixed reviews about the Vanke mod, is it more than cutting the plenum divider down? Any drawbacks to doing it? Also,Scott how do you feel about replacing the 625's with 750's. The twin 770's were not too much, so I wonder if I am undercarbureted. I may drop Mr. Dudek a line to see what it would take to make the stock manifold viable.
