Has anyone used the lt4 hot cam, zz9, or zz9x with the tpi system? Considering using one of these cams if I can pass emissions with either of them???? I have a new engine with afr 190 heads, ford svo 24lb injectors and a ported intake system with slp runners. Also, tes headers, 3in exhaust w dual cat's, stock rear end gears, 2000 stall brand new pro built tranny. Just wondering if anyone has used this cam with the tpi setup adn if anyone has had any problems passing emissions? future mods are super ram, I would go with the stealth ram, but I want to stay emission legal.
