This is a lost artform. When the mods came out, people forgot these kind of "adjustments" the old school guys used. You can say its stock to the sap who wants to run, he won't have a clue. While you're there, you can drill the nitrous ports on the underside. Most guys, especially anymore, couldn't guess thats done till they're separated from several dollars. Sneaky is a point of view, I liked the term "innovative"

Set of properly done Thumpers, port job on the lower, E cam, low 13's all day, looks bone stock- this sounds like my car! PM me if you wanna sell one!
