OK, so I am padding my post count a little tonight. Below is a pic of the TBI setup in my 55. I am using a corvette header that was only used on corvettes between 1980 - 82, I think. They are not rams horns and they have 2.5" outlet. As you can see, I welded shut the rail air openings. Because my 1975 pig is SMOG EXEMPT I also have set of shields that cover them and prevent the wires from contacting the pipes.
