If Im not mistaken their articles showed that the 70mm combo netted substantially better gains across the curve and more peak hp than the 75mm unit. Don't be tricked into the "bigger is better" game. A 70mm setup flows MORE air than all but the wildest NA engines can use, so going to a larger throttle body will NOT lead to more airflow into the engine, as a matter of fact it will decrease the cylinder filling capabilities because of the reduced air velocity.
A 75mm helps forced induction engines more than a 70mm because they don't need velocity - the air is gettin forced into the engine.

Ya sounds good. Let me know how it goes. I have it set up where I can remove my stereo equipment in five. o minutes when I get to the track. Those are the same speakers I have. They THUMP! When I bought my car, I got the base model. I don't even have the 460.

RE: throttle body and intake plenum
what size is the throttle body on a Stock GT? also if you get a bigger TB how will that affect you getting a CAI , like the KandN people are gonna give you a intake for a certin size TB and if yours is bigger , well, it wont fit?
