I am showing 89 in lbs for all pan nuts and bolts except the two rear bolts which are 18 ft lbs

 

I have no idea what's going on with the front studs on this. I've actually tabled finishing this and started putting some new brake hardware/front suspension hardware on until I figure it out. I've had to acquire a couple new studs/nuts (studs are discontinued), and check the gasket to make sure it didn't split. I also bought a better torque wrench.

This is where I got the numbers, pdf shop manual. My Haynes says the same, but I'm sure they get it from the GM manual. 24 lb ft seems high and I'm totally afraid of even trying it again now.

 

I see now in my book has same thing on those pages, at 6a2b-53 is where I looked. that's strange.
