727 big block trans converter tighten/untighten tricks

Yea you can torque-wrench them.
What I do is move the bolt that I want to torque , to a position where I can access it. Then I put a Vicegrip on the flexplate , over and around the ring gear, and jam it up next to the block/bellhousing. Then turn the engine over by hand until the Vicegrips jams onto the ring gear and locks it all up. Now she's ready to be torqued.

Great idea. What do you use for a torque wrench setup ? I can only see using a torque wrench on a long extension with a flexible socket perhaps fitting. There is not much room down there between bolt head and oil pan for a standard 3/4 socket and rachet setup.
