what are the torque specs for not the oil baffle nuts but the studs that the nuts screw to, also what are those studs called?

Re: Torque specs

I'm assuming that you're looking at the Bottom of the motor,.......

Those would be the Main Bearing Bolts........
The Windage Tray is then nutted to the shorter studs......

I don't have that # handy,....
But searching for the Main Bearing Bolt Torque should find it Quickly.........

Re: Torque specs

Main Bearing caps on the 4.3 (V8's may be different, but I doubt it) get torqued to 75 lb./ft. according to the FSM.

Not sure about the torque values for the windage tray.
