I seem to remember that someone on this list
posted that the transmissions were tested during
development by jamming them into reverse at
highway speed. Development continued until the
transmissions would survive that treatment.

Originally the 442 indicated 4 barrel, 4 speed, and dual exhausts. Or
something like that. And yes indeed, it would turn the tires. Worked on a
bunch of those. That 4 speed was almost indestructible. Hell for strong.
