I have an aftermarket, 4x4 specific cast ehaust manifolds. As you mentioned it takes long header pipes for torque, but that puts the collectors down in harms way, and if the collectors take any type of decent hit the reulst is usually an exhaust leak up and the header/head mounting.
The QJet is a 750 CFM while the Edelbrock is a 600 CFM. Some folks have told me that I would never get the a 750 CFM to do anything but run rich given my application and altitude. You also mentioned fuel injection. What is out there in the way of kits? General pricing?
