I say go for it man. Im looking at comp cams as well but havent really made a decision on any. Youll definitely keep your torque with the navi intake it probably just wont make as much power up top.. and definitely wont look as cool
I really want to go with the boss intake or possibly the stock 5.0 intake with a relocated alternator and then use like an 80mm bbk throttle body. If I can frankens tein all the pieces together I think itll be a badass build that makes some badass numbers. Im a sucker for having one of a kind things.
