LodiWino You left out a couple of things, how big is the camshaft in your 482, how much vacuum you have at idle. What is the system of the ECU are you running? What RPM are you trying to idle at? If you are running a solid camshaft either solid roller or flat tappet, Idling is the worst thing to that motor. I don't know which stack system you have but on some you can install an Idle speed control motor from a GM car in the mid 80's. It will work in the place of an IAC. TWM and Gessford have an Idle block for EFI Throttle body systems. You would need to custom brackets for this to work. Rick L. Fred this thread was back in Sept.
