I use a cheap Harbor Freight ratchet strap under the back of the oil pan wrap around the torsion bars on the stick shift motors I work on when the tranny and or bellhousing is out of the car
I use to stuff a 2x4 in between the bottom of the oil pan and the steering link between the idler arm and pitman arm, no more Neither one of those arms are designed to hold weight on them, especially the weight of a BB motor
