In a Dealer Match-Up of Plymouths's two most popular 1968 Street Musclecars.
1968 Barracuda 340-S Fastback
340 /275 HP
Car Weight #3110 lbs.
1968 Road Runner 383 {Pillared Coupe}
383/335 HP
Car Weight #3424 lbs.
The NHRA did re-factor the 340 from 275 Horsepower to '310' for the 1968 Season. And the NHRA
classed the 68' Barracuda 'Fastback' in E/Stock {10.00 to 10.49 Wt/Hp}.
Though the 383 was a 'Torque-Monster', the 335 Horsepower Rating was always questioned. The
NHRA also class the 68' Road Runner in E/Stock.
The 'general consensus' was, that the 383 was over-rated by at least 30 Horsepower from the
Chrysler Factory, and the 383 was really closer to 305 Horsepower. And the Road Runner should
have been classed in G/Stock {11.00 to 11.49 Wt/Hp}.
By June 1968, the NHRA National Records were;
E/S ........ 12.78 @ 107.65 MPH
E/SA ...... 12.79 @ 109.75 MPH
