360 torque

Back in the day when I was learning, and when this vintage of engine was in production, I was always taught to torque them with dry threads. I'd be interested to hear others say what they have learned on the matter.

Being oiled when they are supposed to be torqued dry will lead to considerable increase in clamping force, bolt tension, and block distortion. But I suspect you are right that they will torque more evenly with lube.

The torque specs are as the parts were delivered to the factory. Whatever coatings that they came with were what they developed the torque specs for...

Adding oil to the threads and/or below the head will affect the coefficient of friction for the bolt, which will affect the clamp load at specific torques... Too much oil can cause more stretch for any given torque...

I always run a tap and die down any threads that I reuse and torque them to spec dry...
