Let's get a thread together of all the various torque specs on the engine and tranny bolts. If we can get some good info here maybe we can turn this into a sticky.
I will keep this post updated as we add more specs. Some to start us off - fill in what you know:
Valve covers - 9 ft/lb
Head bolts
Timing cover - 18 ft/lb
Crank pulley
Accessory brackets
Tranny bellhousing bolts
Flexplate
Engine mounts
Exhaust manifold or header bolts
Oil pan
Timing gear
Cam retainer plate
Rocker arms (stock) - 22 ft/lb
Transfer case bolts - where they attach to the tranny tailshaft
Transfer case bolts - the ones that hold the two halves together
Torque converter bolts
PS pump
A/C compressor
Let's see what you all know

I think we should make a chart and have everything at our fingertips when we need it the most rather than farting around online for an hour while one should be turning wrenches. 
Oh yea and
Crank bolt- Herniate yourself and it still wont be enough.

I purchased a manual for building LS1/LS6/GenIII motors off eBay for about $20 shipped. It was a huge wealth of info that I could bring to the car or bench whenever I needed it. ALL the required torque specs were listed by ft/lbs and a few in/lbs ( like valve cover bolts ).
Having it online would be great but I whole heartedly recommend purchasing a manual.
Oh and FarmerBeau is right on, crank bolt spec = hernia.

I have it too! We should get a chart together anyway and make it a sticky!
