All fairly stock motors, what does your Fox idle at?

A little while ago I posted a question about why I might be having problems with my 87' GT's surging idle after a new intake install and I was guided to the surging idle page which helped me out alot and helped me fix my problem. I ended up buying a new IAC which solved my problem. My car now idles about 800RPM or so and I was used to about 1k idle (acording to the stock tach anyways). I figured I would ask out and see what everyone else is at.

Thanks

My car used to idle around 700-800 before I touched some things. Now it idles around 500-600 and is having some troubles which I will soon have to tackle. I'm not comfortable with it at 600 at all. 800 sounds about right.

I had the ole surge problem too, had to clean the IAC, recal the TPS and adjust the stop screw on the TB. Was loping at around 550 now its at a smooooth 800. I think 800-900 is the norm from what I've seen around the forums for a stocker.

Both at 650-700, depending upon electrical load.

Once guys start doing HCI's without a tune is where the higher idle can be needed.

old engine with stock cam would idle nicely at around 600-650. The new engine with the B-cam idles best at like 750 or so...
