For the life of me I can't find any details on what to torque those bolts? Please Help!!! I need all bolt torques for the bolts in the motor mounting area. Also the clam shell type motor mounts. 1976 Chevy K5

Proper torque is critical in all situations so my severe OCD and mechanical knowledge tell me, grunts and groans are not accurate, there is a spec somewhere I'll dig my book out later try to find you a number.... Also remember Loc-Tite is your best friend....

I’d bet you’ll have a tough time finding that in a repair manual. If you just have to have a number then google the torque spec for the bolt size (and grade).
