Did mopar ever build a motor with 300* duration? I love reading these head to head threads and see the mopar almost always out cammed but still winning or giving a run for the money.

Yes,

Street-Driven,

The 1962 ~ 413 'Plymouth Super/Stock' and 'Dodge Ramcharger' engines hit the {300*} Duration Mark.

As well as the 1963 and 1964 ~ '426 Max-Wedge' engines.

The 1964 and 1965 Race Hemi's were a different breed of course.

The 1966 Dodge D-Dart was at {284*} Duration.
