: Need a reliable source for Northstar Torque specs

01-29-08, 02:10 AM
I am timeserting a 98 Northstar engine and was looking for the best place to find current torque specs for Northstar head bolts, cam shafts, and oil pan for example. I found M11 cylinder head bolts first pass 30 ft. lbs. , second pass +70 degrees, third pass +60 degrees, final pass + 60 degrees. Does anyone know a good source for newest torque settings?
