Highly recommend you download the GM Heritage site's pdf information book for '72. It has this spec as well as eight-hundred and 29 others.

454 auto (in drive) = 600 rpm.

deland,
All those numbers in books, manuals and charts are merely suggestions. Nothing is written in stone and every car / driver is different.
You set your idle to your liking. What ever is comforatable to you.

Set it somewhere between embarrassing stalling and having to footbrake constantly.
