How long should I really let my 02 QC 4.7 warm up in the morning?

The way I understand it, you let it sit idle for about 30 seconds, long enough to circulate oil thru the engine and get the juices flowing, then drive it gently until it starts to get some temperature up.

actually, what i was told by a few mechanics, was to start it, let it settle(starting always revs the RPM) then go. if you actually sit and warm it up, it will take much longer to actually reach correct operating temp. this of course only pertains to newer cars(what is considered old i dont know, but i warm up my '79 or else it doesnt run right for about 5 minutes til its warm)

I usually just get going, but drive easy on the throttle the first 2-3 miles.

thats probable the best idea. the best of both worlds and all.
the main reason you want to take it easy on your car during its low temp stages is because pushing it causes uneven heating patters.(ie the pistons heat up significantly before the block itself) if this happens then the pistons edge the sides to the cylinder wall, causing very uneven wear. ive never really heard of an instance where an engine was damaged on one cold run, and competition/race engines tend to be built for this(since cars tend to run better a little cold) just dont make a habit of it
