Why? Because I have it. I have an ls6 bumped up in cubes to 427 and LS3 heads. The 102 is on since the cubes are up and the ls6 manifold won't work. need to put on bigger injectors but I have the smaller size ls7 injectors in hand. bought the Fast accessory that should lift it up some to fit the nxl injector base in the 102 intake. Hopefully that will set up. NX says that the base was not designed for the higher psi of the bigger injector. They recommended to go direct port. I really don't want to sell the one I have and get the newer setup as I will take a big hit on cost. Anyone got this setup in their car?
