need some torque specs I have a lq4 6.0 out of a 02 escalade and I need main cap torques and rod bolts..I'm using the stock bolts and the torque specs I'm findin are like 18ft lbs. And the last thing I want is to not tighten them down tight enough and throw a rod or something so can someone please give me the right torque specs...need them asap so I can put my engine together, thanks
