I wonder the best way to ship you a mess of intakes, I have car and truck early 5.7s and car and truck eagle intakes. My truck 6.4 intake is burned on the top so no use but to look at. I guess only the early car intake will fit your block, the 6.4 truck intake looks like it will fit an early block, doubt an SRT 6.4 will fit it butt maybe. I think only the BGE, 6.1 early car, and early truck intakes fit your earlier block (I assume your running an early block because of the 6.1 cam).
