Car and Driver (October 1967)
Found that the Charger 383 had a 'special driveshaft' with a round-disc
welded to the front of the driveshaft called an
'inertia-yoke' to help
eliminate vibration.
Part #2852162 (3.00" tube diameter driveshaft)
And the 383/330 HP with the 727 Automatic Transmission had a
'special' 10.75" (2350 RPM Stall) Torque Converter (Part #2801764).
Their 'Press Test Car' was equipped with a Torque-Flite Automatic
Transmission, 3.23 Gears w/Sure-Grip, and Red-Line F-70 x 14" tires.
Performance Results.........15.35 @ 91.7 MPH
Note; 'Car and Driver' Magazine was dissapointed, as the original 'Test Car'
was supposed to be a 4-Speed Charger 383, but the car experienced
electrical problems and was not delivered to the Magazine test location.
