I need the inside and outside diameters of the 328 throttle body and the overall thickness of the 328 plenum. I have a 308 4v plenum and throttlebody on my 328 motor and want to know if there are any differences.
Sorry to revive an old thread but did we ever find out if there are any mechanical differences between the QV plenum and throttle body and the 328 one (other than the paint and "3200" script). Thanks.
