I don't torque mine. Just hit the nut with an air wrench. If you want to torque it, you could drop the inspection cover and hold the converter or flywheel with a large screw driver.
I use the flywheel/torque converter method.

I remember using the screw driver in the ring gear method, but I was afraid of breaking a tooth off? I did use an electric impact and was careful not to go too far, maybe that will do? Wonder why they want that so blasted tight?

Thats what I used on my 440 couple weeks ago, electric impact. 1/2" drive, let hammer about 5 times, same as it took to break it loose.
I've never used a torque wrench on that bolt either. A few hammers with the impact and it's done. Never had one loosen.

Same here. Whatever the impact wrench drove it home at was fine.
If I had to lock the engine, I jammed a HF screwdriver into the flywheel ring gear.

Pull a spark plug and fill the cylinder with rope. Get it at half travel to reduce wristpin load.
On the compression stroke.

I made a tool that attaches to the damper with the pully screws. It's a lever about a foot long.i hadn't air tools at the time.
135 pound feet isn't that much really and a few wacks with a gun will likely torque it to a higher value anyways.
If concerned use some loctite

Great idea, I have one of those for holding my Toyota Tundras, but the Plymouth has no bolt holes in it except for the center one.
