I'm putting my 305 back together from my 1990 Camaro RS. My first question is that I have put back in the lifters and am bolting on that spider looking plate (don't know what it is called). It is held in by 3 bolts I haven't been able to find a torque setting for these any idea what it could be? Next I have attached picture of the passenger side of the motor. There are two sensors that I have circled, they were not hooked up when I pulled the motor and have no idea what they are or what they do any help would be appreciated.

 

Torque goes with hardware size. You don't need a "spec" for stuff of that nature; just, appropriate to their size. Which will be around 16 ft-lbs or so for that size screw.

The things in the pic are the fan switch in the head and the knock sensor in the block.

 

Thanks for the info.
