Do I need to properly torque a 350 flexplate to a 350 chevy motor? If so, how so?

Just tighten the 3 sets of bolts with some box or open end wrenches. YOU DON'T WANT THEM TOO TIGHT. I think factory is 30ft/lb but I just tighten them by hand. Never had one come undone yet.

responded to your other post. but if your talking about the bolts into the crankshaft(6 bolts) 65-70 ft lbs. hand tight is about this.
