From previous experience, its more than 74ft-lbs with moly lube. I installed to the gm spec 74ft-lbs and had to pull my tranny to retighten when unexpected vibes from the tranny mount caused my bolts to back out.
if you're using arp assembly lube on arp bolts, 84ft-lbs. If using arp bolts with red loctite, 74ft-lbs is my guess.

Anyone wonder how you get an accurate torque with the plate load pushing against the head of the bolt? Seems one you have the plate bolted down to were its flush, the torque wrench will click without any additional rotation.

Dang, not even close, PP bolts are in the hood of 45 to 52ftlbs.

Hope you are tightening them all a turn at a time and pulling it down evenly. I pull them all like this, torque each bolt in 3 stages to the final value, then go around several times at final value to make sure nothing moves. As a side note, once all bolts are down, pick one and you can remove it (almost) by hand as the others hold the plate down.
Hmmm....I wish I had that idea last night. Its already back together
I cris-crossed the tightening sequence, and went around the wheel ensuring they were torqued to 52, but they already seemed to be about that tight already....

I have been installing clutches for years and just now I realized that....But I guess if the pressure of the PP is pushing back, I assume the bolts are stretching to ensure clamping force? I don't think anyone really has dug this deep into it...
