All 6-bolt 4g63 have the same torque specs.

You're probably thinking '92 and up (build date) which corresponds somewhat to '93 and up (model year). Like was mentioned above, the only difference is 6 bolt vs. 7 bolt.

The VIN is stamped on the block.

 

ok so what year did they start 7 bolt

and my owners manual says 51 ft lbs for 92 and earlier and 92 and later is 18ft lbs and an extra 90 degrees thanks

6bolt: 51ft-lb
7bolt 18ft-lb + 90*

 

Thank you guys

To determine if its a 92 and up (i.e. 7 bolt block) you can tell by the shape of the oil pan. I'm 99% sure the info is on VFAQ.

4th month of 92 is when the engine switched over to the 7 bolt.
