Track heat is a great intake but you won't reap the complete benefits of what it can do unless you running some trick-flow heads also. trick-flow parts are real finicky about working well together. I'm sure a trick-flow intake will work well with some gt-40 heads, I only suggested gt-40 everything, cuz for street performance you can get a pretty good gain, and it's relatively cheap. hit up local junkyards, find yourself a 302 exploder or mountaineer and bang, there ya go. most junkyards will sell it to ya stupid cheap to, cuz they dun realize it's actually an upgrade for a stang.
