I've got a 78Z that has had a larger throttle body and AFM added. The air control valve has been removed and, the TB doesn't have a port for the ACV. (runs terribly cold - thermotime & cold start are fine) The EGR has also been removed and been replaced with a metal plate. (we don't have emissions testing in this part of TN.) I'm wondering if I could replace the ACV and plumb it somewhere other than into the TB. Would it do the job plumbed for example to where the EGR used to be or does it need to be near the front of the intake?
