Maybe that is a dumb question.... Looking at the stock 500 tb it looks the same as mine. So i guess a better question is are the 500's tb different than the stock gt.

I think stock Gt is 57mm, Gt 500 is 60mm.

Ok... I might just put a 62mm bbk i have on instead

GT500 throttle bodies have a different bolt pattern. Keep your stock one if you install that BBK plenty of guys have had problems with that thing...not to mention your stock unit is not a restriction at this point.

I think i saw adapters for the gt500 to fit on the gt. Ill have to look at it again

You did see them. What [email protected] is true though. There will be NO gain in horsepower at your level of power. It is not a restriction. Until it is, you gain zilch! Some cars gain power off of certain mods like a throttle body right out of the factory. 3v mustang is not one of them. I've had one...BBK 62mm. Btw stock is twin 55mm.

What is the point where it will benefit?. Part of this is bc when i did my install and switched tb i noticed while holding it that the stock didn't seem to return very well when i opened it... Wasn't sure if that's just how the stock operated or maybe a weak spring.. But while idling if u rev it up it doesn't return to return reg rpm as it use to. And again could be bc i was use to the bbk or my stock isn't working proper. Rather then buy another stock thought i would check out the bbk that's just sitting in a box

The throttle blade angle is set by the motor on the TB. If it wants to close slower it simply "powers" it shut. The speed the TB opens and closes is done through the ECU.

Your stock TB will not be a restriction till 400hp NA and 500HP blown.

Use your stock TB.
