Large valved 273

I remember an old Mopar Action, or maybe it was High PerformanceMopar, a guy bulit a 67 Dart 'vert with a 273 that ran tens. Maxed out X heads, big solid lifter cam, tall single plane, the works.

It was "Mopar Action" story was "Darn Dart".......273 with "X" heads, TRW pop up pistons, story said .509 MP cam, don't remember intake, 904 trans, 4.88 gears (I think), ran in the 10's..........others can fill in gaps/corrections
