74lb-ft is correct for the flexplate to crankshaft.

straight from GM

1. Tighten the engine flywheel bolts a first pass in sequence to 20 N·m (15 lb ft).
2. Tighten the engine flywheel bolts a second pass in sequence to 50 N·m (37 lb ft).
3. Tighten the engine flywheel bolts a final pass in sequence to 100 N·m (74 lb ft).
