So while I don't have the racer x intake manifold, I really wanted to get that super freaking bad. But I do sell ported intake manifolds and I do have a set of 60 lb ACDelco injectors and a set of 80 lb ZZP injectors. If you're looking to buy those. If you go with the bigger injectors then you're going to need a tune. I also offer tuning services with Hp tuners and EFI live and I can do remote tuning with you
