5.7L TBI idle RPM?

Anyone know what the idle speed should be for 1993 5.7L TBI, both in part, and in drive, once the engine is at operating temperature?

As I mentioned in a previous post, I replace the IAC valve, and my stalling/low idle/surging problems are gone. The engine fast idles at 1100 or 1200 RPM when cold, settles down to about 900 in park, 750 in gear.

I did some Googling for about 20 minutes, and can't find the specs anywhere (I don't have a tuneup guide). The owners manual doesn't mention the idle RPMs either. Any one help?
