Stock exhaust manifold, Crower Intake Advertised lift 434 Duration 291 Exhaust Cam is slightly different, very slight. Skunk2 adjustable cam gears, Titanium valve springs and retainers. Stock throttle body, stock injectors and fuel rail. It lost bottom end power and it feels the same as before at about 5000 and up. Planning on turbo soon. But would like some more power right now. Whats up with it. I was hoping for a little increase.
