I was just joking around earlier, but never the less, I feel vindicated.
Chains are darn handy on cars too.........
Back around 1970, the '68-69 Cameros had a problem surface with the higher performance engines in them torquing up & out of the motor mounts. When it did it, the throttle would jam wide open----- and off ya go until it hit something big enough to stop it, or ya ran out of gas. We're talking engines of 300-- up to 500 horsepower in a car, that really should have been limited to the old 145 cu.in. 6 cylinder.
The factory (warranty) modification, was to put a snubber chain from the frame to the engine block. When the motor mount tore apart, and the engine tried to climb/twist up & over the one on the other side,,,,, the chain stopped it.
