Post your favorite Mopar Myth.

348/409 is an older/different design block than what everyone thinks of as BBC.

Impala/Caprice w/400 badge had small block (after 70 IIRC).

Truck w/400 badge had 402 big block.

nova/camaro/malibu with 396 badge had 402 (after 69).

Why do I know this? I should have purged this a long time ago.
