65 ftlbs, in a star patten so it's pulled down evenly. Wouldn't hurt to do it in steps either. Start 40 each then 65 each.

Make sure you use red loctite on the threads for the flexplate bolts as well... those are some bolts you absolutely, positively, do NOT want to come loose. I also used blue loctite on the TC bolts
