Hey whats up guys, just a couple of questions. I have a 90 fox GT and a 90 Grand marquis both with 302's. Questions about the HO and non HO, is the marquis a non roller? The intake plenum goes the other way on the marquis, other than that what are the differences between the two? The 90 gt mustang is def. a roller right? What would be a good injector/maf/throttle body combo to start with on the stang? Its all stock. What are stock specs on factory injectors? Thx!
