Does anyone know that the torque should be for the
flywheel nuts?
Should they have a carter pin in them?

Can't help you with the torque spec, but if the bolts are drilled I would assume either a cotter pin or more likely a safety wire was intended. If you can't find a direct answer on the torque, Google "torque for a 1/2x18 (or whatever size they are) bolt" and you should get a ballpark idea as below.

They are cotter pinned. I don't remember the torque we used, but I will try to check the notes when I get to the shop tomorrow. I am pretty sure we used a similar source for the torque setting as provided by Packard8.
