Even the NHRA felt sorry for the 383/335 HP.
First refactoring the Horsepower down to 310 HP, and then again, down to 300 HP.
The 1968 '383' Road Runner or '383' Super Bee were 'no match' for the 340-S Barracuda's or 340 GTS Darts in E/S or E/SA in 1968.
Every Car Magazine performed 'Accelerated Timing Tests' on either the 383 Road Runner of 383 Super Bee.
Of course, with either a Standard 3.23 Gear Ratio or {3.55 Gear Ratio; Performance Axle Option}.
Note; The 3.91 Gear Ratio was only available through a 'Direct-Called' Special Factory Order.
In other words, 'you had to know somebody' at the Plymouth or Dodge Performance Sales
at the Regional Office.
