Basically the question at hand is will a pulse width modulated iacv work on an lt1? I know the factory one is a stepper motor..
Trying to make edelbrock 39783 TB work with the factory computer..
Do I need to change iacv or just get a different throttle body?

 

Well to answer my own question
This throttle body won't work with a factory computer

 

If you're not set on that particular style of TB you could see if Aaron over at 6061.com could build an elbow for an LTx style throttle body. I have one of his LSx elbows and it's an awesome piece.

 

I know this is an old thread but is the newer tb you wanted to.use similar to the lsx type of throttle body if so , if one were running a 0411 pcm swap im sure you can run a newer style IAC.
