Motor mount torque spec?

[ascuro]

Where would I be able to find the torque specs for a motor mount to engine block? (70 blazer, crate 350, if it matters). Neither Haynes or Chiltons seems to have it listed.

I'm guessing around 30-40 ft/lbs if I can't find it. That sound about right?

Standard torque for a grade 8 3/8" bolt is 35 +/- 7 ft/lbs. I've seen motor mount bolts be very problematic and they are surely a pain to get to once the engine is installed. I'd thoroughly clean the bolt and the hole, then torque it to 45 ft/lbs using red locktite.
