Torque specs

I just started disasembling/cleaning/painting the 1983 351w engine and C6 tranny that i am building up to put in my truck (unless a good used mustang crosses my path!). Does anybody have a complete list of torque specs for this engine, or a internet link to them? I need everything, rod bolts, cylinder head bolts, bellhousing, torque converter, etc.
