Engine Mount Stud-to-Engine Block - 37 lb ft

Engine Mount Through Bolts - 70 lb ft

Engine Mount Through Bolt Nuts - 59 lb ft

Engine Mount-to-Engine Block Bolts - 37 lb ft

All i wanted to know was the torque spec for the engine mounts for my ls1 GTO. Thought it was 1 nut that holds the mount to the engine, therefore one torque spec. A searched yielded the above and now im confused.

Could someone please explain what exactly are...

1. Engine Mount Stud-to-Engine Block (is this the bracket?)

2. Engine Mount Through Bolts (no clue what this one could be)

3. Engine Mount Through Bolt Nuts (?)

4. Engine Mount-to-Engine Block Bolts (?)


Thanks a lot in advance!

1) this is a stud that threads into the block and holds the upper bracket to the block

2) this is the long through bolt through the rubber/poly mount. This is the value to torque the bolt if your torque wrench is on the bolt head, and you're holding the nut still.
