I would try and help but I can't understand what you're saying. Please retype your post, this time using the "." key.

If the engine is stock, the idle is supposed to be around 600 or "6". Sounds like you may have fixed something by accident.

 

Sounds like he may have fixed a vacuum leak. When you were unplugging the MAF, you were putting the computer in "limp home" mode, which may be why it idled up. Someone will correct me if im wrong....

 

When i start it runs fine and it was a 350 before now its a 350 but stock comp ntn done to prom and it kind of sounds like it will shut down on you when its idle but dosnt if any if this helps

 

My '87 IROC idles around 600-700. It is a carbed 350, not a TPI like yours (was idling around 12-14, but I don't think the PO knew how to tune a carb because my dumb *** did it in the span of 30 minutes when I got it home). It also sounds like a real slow, throaty growl but it stays running. You'll get used to it. Like hdis2002 said, I think you fixed something while you were cleaning stuff up.

My take is this: if you idle down the strip with your engine rumbling like it should and you get panties thrown at you then everything is working as it should. :-)
