Anyone out there have the torque (bolt) specifications for the ZZ4 engine. Putting mine back together with new pistons. Thanks.

 

I have seen the torque specs before but it was a long time ago and I cannot find them now. Try calling Sallee Chevrolet or Jim Pace and maybe they have them. I looked on their web sites but could not fine the specs. I'll keep looking, maybe I have them in a notebook somewhere.

 

If you haven't got an answer by this evening I'll check my install book...
