On long story short my ex father in-laws managed to crush my IAC I found a replacement for a decent price but will a 3.8 IAC work on a LT1 I'm on a very strict budget and gonna try to save money if I can

 

different part numbers, i would say no. did you compare at parts store? maybe try that. i think they run on different volts.

 

My guess would be that since they have very different flow requirements their designs would be different.

 

Thanks for the input I can find v6 camaro all day where I'm at finding a z28 is the needle in the hay stack in the junk yards

 

Here is the cheapest one for LT1 I found for $12. I don't use it on a car, but on a PCM test setup. It has been working for 2 years now on an occasional basis. Definitely made in China. Link may not work. Search for "New Idle Air Control Valve IAC 17112478 AC27"

just buy one for $ 10.00 like said

 

If you have the flat plug that bolts in, you can use one off the 3800 series engine. There's something different about them, I don't remember what I will try and find out, I do believe it was just the way the plug was oriented. but I do remember it will plug in and function the same at a less price.

 

Don't forget that the Buick Road master and Caprices came with Lt1s in anything with a tow package. It is very common in those wagons 92-96.
