Default Throttle Body Torque

I'm rebuilding a '93 LT-1, VIN P throttle body. The FSM doesn't specify the torquw for the seven screws that hold the bottom quarter to the top, nor does it mention the six screws that hold on the top of the throttle body.

Any ideas?

Thanks,

Larry...

I wouldn't worry about torque, just snug them up.

Thanks. As you suggested, I snugged 'em down and that seems to be 40 in/lbs. I think they feel good.

I put some thread sealant on the bottom bolts where the coolant flows after I had took apart and cleaned up the throttle body on my 89. Just to help prevent a possible leak. The screws were a little rusty, so coolant had been getting to them. I just tightened all the bolts down to where they were tight.

One thing I liked is I had no gasket stuff to clean up. The OEM gaskets were rubber. I sure wish they still made rubber gaskets as I had to use paper.
