The "S" intake (in 2V and 4V form) is NOT a 390GT intake. It is used on the 390GT only because it's what Ford had laying around, and Ford didn't wanna pony-up the bucks to stick a nice PI intake on the motor as it should have.
The "S" intake is an all-new "equal runner" design, made to assist the FE in passing emissions in 1966 and later. It borrows some lessons learned while designing the 427MR (and by extension: lessons learned with the 427HR intake), but it only borrows features which aid combustion efficiency (aerodynamics and balance between cylinders) and NOT any of the performance elements. The "S" intake was stuck on the 390GT as well as on Country Sedans and any other FE they were building from 1966 and later. The "S" intake is the FINEST mild cruising intake ever designed for the FE. It offers excellent airflow velocity characteristics, promoting fast starts, the smoothest idle, and quiet strong acceleration. It ain't a racing intake by any measure. It should sell for $50.00 tops, because about half the FEs made since 1966 had them (in either 2V or 4V form) and they never wear out or break.
The "T" intake (2V and 4V) is identical to the 1958-65 FE iron intake, except it interited shrunk runners at the last inch or so where it blends to the "new-for-1966" emissions heads, which have smaller "velocity" runners and needed to have the 1965 intake runners modified to flow properly. Except where it blends to the head, the "T" intake is identical to the 1965 iron intake. Again, because about half of all FEs since 1966 got this intake, it should sell for $50.00 tops.
I'm not gonna look-up the intake part number, but assuming you have an iron 2V or 4V intake in that C5 piece, it's just the standard FE intake (Ford called it the "Dual Plane") - a design that lasted from 1958 through 1965, with changes in the road-draft tube, oil filler, carb flange angle, vacuum holes, and thermostat hole diameter about the only variables you'll find.
