There are quite a few different ways you can go with GT40 setups just because there are quite a few GT40 options out there. For intakes, you have the Explorer intakes, Cobra intakes, and the tubular intakes. Generally believed that the tubular models flow a little bit more, followed by Cobras and then Explorer's. The lower intake is the same but the uppers are different. Unless you use a 94-95, like rz5.0 recommended, you will also need an adapter elbow or to convert your car over to fox T/B setup.
