Throttle bodies and Intake Manifolds Matching up

[kpack5982]

I am going to get a new intake manifold but was kinda wondering about what size throttle bodies fit which manifolds. I've been searching the forums for about two hours and found nothing like this in particular, so was wondering if there is different sizes that fit different intakes or what the deal was. Also was lookin for a cheap intake if anyone has one for sale. I'm kinda lookin for a gt40 or something like that. figured since I gotta replace the head gaskets i would do that at the same time. The owner before me ported the heads so not going that route quite yet, but any and all info would be great

Stock cobra manifold will support up to a 70mm TB without the need for a dremel. (I believe the cobra mustangs came stock with something a lil smaller though like 65.

Dunno about the gt-40 though. its very similar to the cobra so it may have the same size opening... only problem with the gt-40 is that there is hardly any room to open it up at the tb location. I hope some of this helps.

trickflow

What about with like a trickflow? Also, should i just wait until I actually purchase my intake? I think i saw somewhere like 75mm for that application
