Looks like mine's just a hack job that someone pawned off as the real deal. Here's a pic that shows how both plenums are totally hogged out. I recently bought one from John Arruzza, to go w/ a larger cam (solid flat tappet) & 750 eddys, but am worried that I'll loose a lot of low end & mid range. A Stage 5 intake will make a lot more power & torque, but will loose the stock look. I'm also concerned about the correct height for my Shaker.
