1968 Road Runner '383' vs. 1968 Competition

For durability,

In 1968, the Road Runner and Super Bee {383/335 HP} were the best of the
mid-size Musclecars.

The drive-train was 'beyond' durable, it was indestructible.

And I don't ever remember a 383 coming into my father's Machine Shop
that was 'blown up'.

Even the tired ones would hold up.
