I just went to" bolt down" the SC on my 3800. The Book says the "Torque setting" is 8 Pounds. Is that a misprint ? Why not just say "finger tight and a smidgen" ? HOW can it "seal" like that, My torque wrench doesn't want to really "Click" at 8 pounds. Would I be better off using an "INCH Pound" wrench ?

You bolt it down at 17ft-lb, go around starting from the center in a criss cross pattern. Do your passes like 5lb, 8lb, 12lb, 17lb, 17lb, 17lb , turn the pulley with each pass to make sure it is not binding up.

17 iis more reasonable. I thought it was a little strange torqueing the intake to 11, but then 8 !? Is 11 correct for the intake manifold bolts ? it's an aluminum manifold, not plastic.

11 is the correct torque for LIM, however with aluminum gaskets I went with 15lb on my Fiero 3800, original spec is for plastic gaskets... But you should be safe anywhere from 11-15, I went 11 on another 3800 engine 50k miles ago and it's still going strong with no leaks. Don't forget thread sealant for threads and anaerobic/GM assembly sealant for the corners.

Where do the intake bolts thread INTO ? water jacket or just exposed to oil ? Forgot to look.
