Post your favorite Mopar Myth.

Speaking of "Myths" what exactly is the Mopar 408? Was that built off a 360 block or am I wrong and its a whole design by itself, for crate motor offerings?

I'm still perplexed at that one! Would have been a GREAT 400+ CID offering in a car, even tho, couldn't you technically order that in a custom order car? Road legal that is.......?


Mopar 360 (LA or Magnum) engine with bore of 4.030 (.030 overbore from stock 4.00 bore) and a crank with a stroke of 4.000 is a 408 (408.18 to be exact).
