Bellhousing bolts and torque converter bolts torque specs

I'm mounting a motor (SBC) to a transmission (TH-400) just wondering about a torque sequence and also torque specs for the bellhousing and torque converter bolts. Thanks in advance.

Those are 3/8" bolts, usually torqued to 30-35 lbs.

There really isn't a torque sequence, usually you start at the easiest to reach bottom bolts, and work your way to the hardest to reach top bolts, if it's still in the vehicle. If everything is right out in the open, start at the bottom and alternate between sides going toward the top.

There are only 6 bolts in a half circle pattern, a specific torque sequence is designated to distribute clamping forces of the torqued bolts when a gasket is used, or when a balanced amount of torque is desired especially when wheels are concerned. In this case you are simply connecting two components together.
